Ice absorbs whatever the freezer smells like. That is the actual failure of most trays, and it has nothing to do with cube shape, which is what every listing competes on.
A covered tray keeps odors out and stops water sloshing on the way to the freezer, and neither of those shows up in a product photo. Our roundup of cereal bowls covers what the ice goes into.
Types at a Glance
| Type | Best for | Watch out for |
|---|---|---|
| Silicone | Easy release | Absorbs odors, floppy |
| Rigid plastic | Stacking, cheapness | Cracks, hard to twist |
| Covered trays | Odor and spills | Lids warp over time |
| Large cube | Spirits, slow melt | Too big for most glasses |
| Sphere molds | Presentation | Fiddly to fill and release |
| Stainless lever | Durability | Expensive, heavy |
How We Picked
Selections are grouped by what each design solves rather than by cube shape, since shape is the least consequential thing about a tray. Odor protection and release are weighted heaviest.
Descriptions come from documented construction and materials rather than hands-on testing.
Why Ice Tastes Like the Freezer
Water absorbs volatile compounds from the air around it, and freezing does not stop the process. An uncovered tray sitting next to fish or onions produces ice that tastes of both.
Silicone makes it worse, since the material itself absorbs and holds odors and then transfers them to the next batch.
Old ice is the other half. Cubes left for weeks sublimate slowly, shrinking and concentrating whatever they picked up along the way.
A lid on the tray and turning the ice over regularly solves nearly all of it, which is cheaper than any tray upgrade. Our roundup of refrigerator organizers covers keeping smells contained.
1. A Covered Silicone Tray, Best Overall
Why It Stands Out
Silicone releases cubes with a push rather than a twist, and the lid keeps freezer odors out and water in during the trip to the freezer.
Flexible bases also mean you can pop out one cube without emptying the tray.
Worth Knowing
Silicone absorbs odors over time and needs washing more often than plastic to stay neutral.
Floppy trays are hard to carry full, and a rigid frame around the silicone fixes that. Our roundup of food storage containers covers other covered options.
This suits most households. Skip it if you dislike washing things frequently.
2. A Rigid Plastic Tray, Best Value
Why It Stands Out
Cheap, stackable, and it holds its shape when full, which is more than can be said for bare silicone.
Plastic also absorbs far less odor than silicone, so ice tastes cleaner for longer.
Worth Knowing
Release requires twisting, which cracks the tray eventually and is genuinely difficult with cold hands.
Cheap plastic becomes brittle in a freezer over a year or two. Our roundup of pantry containers covers plastic durability generally.
This suits anyone replacing trays cheaply. Skip it if twisting is a problem for you.
3. Large Cube Molds, Best for Spirits
Why It Stands Out
Bigger cubes have less surface area relative to volume, so they melt slower and dilute a drink less. That is the entire argument and it is a real one.
They also look better in a glass than a handful of small cubes.
Worth Knowing
Too large for many everyday glasses, and useless for filling a tumbler with ice for water.
Takes considerably longer to freeze solid. Our roundup of whiskey glasses covers the pairing.
This suits spirits drinkers. Skip it as your only tray.
4. Sphere Molds, Best Presentation
Why It Stands Out
A sphere has the least surface area of any shape for its volume, so it melts slowest of everything here.
It also looks deliberate in a way cubes do not, which is most of why people buy them.
Worth Knowing
Filling through a small hole is fiddly, and spheres frequently freeze with a flat spot or an air gap.
They take up disproportionate freezer space for the ice produced. Our roundup of cocktail shakers and bar tools covers the rest of the setup.
This suits entertaining. Skip it for everyday ice.
5. A Stainless Lever Tray, Best Durability
Why It Stands Out
The old design with a metal lever that cracks the whole tray at once, and it is effectively permanent. Nothing absorbs odor and nothing goes brittle.
The lever also means no twisting and no pushing individual cubes out.
Worth Knowing
Expensive compared with plastic or silicone, and heavy.
Metal conducts, so the tray is unpleasantly cold to handle straight from the freezer. Our roundup of kitchen tongs covers handling ice.
This suits anyone tired of replacing trays. Skip it on a budget.
6. Small Cube or Nugget Trays, Best for Volume
Why It Stands Out
Small cubes chill a drink faster because there is more surface area in contact with the liquid, which suits soft drinks and water rather than spirits.
More cubes per tray also means a fuller ice bin from the same freezer space.
Worth Knowing
They melt fast, which is the same property working against you in a slow drink.
Small compartments are more fiddly to release from rigid plastic. Our roundup of insulated tumblers covers keeping drinks cold longer.
This suits households drinking a lot of cold water. Skip it for cocktails.
How Much Ice Do You Actually Need
Tray capacity gets ignored until the moment you need ice for more than two drinks and discover there is none.
A single tray produces enough for a couple of glasses, which is fine for a household that uses ice occasionally and inadequate for one that drinks cold water all day.
The usual answer is several trays plus a bin, where filled trays get emptied into a container and refilled immediately. That decouples how fast you use ice from how fast the freezer makes it.
A bin also needs a lid for the same odor reasons a tray does, and loose ice in an open container picks up freezer smells faster than ice sitting in its tray.
Freezer space is what limits this in most kitchens, and stackable trays are worth considerably more than an extra tray that has to sit flat somewhere.
Why Homemade Ice Is Cloudy
Cloudiness comes from dissolved air and minerals trapped as water freezes from the outside inward, pushing impurities toward the center where they stay.
Clear ice is made by directional freezing, where water freezes from one direction only and impurities are pushed out rather than trapped. That is what specialist clear ice makers do.
Boiling water first is the commonly repeated trick and it helps somewhat by driving off dissolved air, though it does not produce genuinely clear ice.
Cloudy ice tastes the same and melts at the same rate. It is purely appearance, which is worth knowing before spending on a solution.
What Actually Goes Wrong With Trays
Odor transfer
The most common complaint and the one a lid solves. Silicone is the worst offender.
Spilling on the way
Carrying a full tray to a freezer without spilling is harder than it should be. Covered trays fix it entirely.
Cracking
Rigid plastic goes brittle in a freezer and twisting eventually splits it.
Sticking
Cubes that will not release usually mean the tray was overfilled and ice bridged across the top. Our roundup of dish drying racks covers washing them properly.
Cleaning and Replacement
Trays get washed less often than almost anything else in a kitchen, on the assumption that water cannot make anything dirty.
Silicone is the one that genuinely needs it, since it absorbs odors and passes them into the next batch of ice. Washing it regularly is the difference between neutral ice and ice that tastes of the freezer.
Mineral scale builds up in trays too, particularly with hard water, appearing as a chalky film that does not rinse off. Diluted vinegar removes it where detergent does not.
Plastic trays are worth replacing when they go cloudy or brittle, since brittle plastic cracks and cracked trays leak into the freezer.
Most trays are dishwasher safe, which makes this a non-issue if you simply put them in with everything else rather than treating them as clean by default.
What to Look For
A lid
The single most useful feature, for odor and for spills, and it is frequently absent.
A rigid frame
Silicone with a stiff surround gets the release of silicone without the floppiness.
Stackability
Freezer space is the constraint in most kitchens, and trays that stack flat are worth more than trays that do not.
Cube size matched to your glasses
Large cubes that do not fit your everyday tumbler are decorative rather than useful.
Common Mistakes to Avoid
Leaving ice for months
Old cubes shrink and concentrate freezer odors. Turning ice over regularly matters more than the tray does.
Overfilling
Water above the divider line freezes into a sheet across the top and makes every cube difficult to release.
Buying for cube shape
Shape is the least consequential thing about a tray. Lid, material, and fit in your freezer matter far more.
Ignoring silicone washing
It absorbs odor and passes it on. Washing regularly is not optional with silicone. Our roundup of dishwasher-safe cookware covers the same material question.

Ice Cube Tray FAQ
Why does my ice taste bad?
Water absorbs freezer odors, and freezing does not stop it. A covered tray solves most of it, and silicone absorbs odors itself so it needs washing regularly.
Silicone or plastic?
Silicone releases far more easily and absorbs odors. Plastic keeps ice tasting cleaner and requires twisting, which cracks trays over time.
Why is my ice cloudy?
Dissolved air and minerals trapped as water freezes inward. It affects appearance only, and clear ice requires directional freezing rather than a different tray.
Do bigger cubes really melt slower?
Yes. Less surface area relative to volume means slower melting and less dilution, which is why large cubes and spheres suit spirits.
Why will my cubes not come out?
Usually overfilling. Water above the divider line freezes into a sheet across the top, locking every cube in place.
Do I need a lid?
It is the most useful feature on a tray. It keeps freezer odors out of the ice and stops water spilling on the way to the freezer.
How long does ice keep?
Indefinitely in terms of safety, and it degrades in taste within weeks as cubes shrink and concentrate absorbed odors. Turning ice over regularly is the fix.
Are stainless trays worth it?
They last effectively forever and never absorb odor, and they cost considerably more and are unpleasantly cold to handle straight from the freezer.
