Prepping Ingredients with Smootheeze

Welcome

Hey smoothie drinker! Thanks so much for trying Smootheeze—we’re thrilled you’re here. My wife and I run this small business, and we seriously can’t thank you enough for supporting us. Now let’s go over how to use the trays and get you set up for hassle-free smoothie prep!

Smootheeze Easy Banana Freeze Tray Tips

Let’s talk about the easy freeze banana tray, the true hero of the bunch. This is what kicked off the whole Smootheeze craze.

Here’s how to freeze bananas like a pro:

Peel and place bananas directly into the tray cavities. Breaking them into halves or quarters makes blending easier later.
You can also slice or mash bananas and spoon them into the trays if you plan to use them for cooking or baking.
Snap on the lid and press firmly around all the edges. Lift one corner to press out the air and secure the corner again.

✅ Prefer banana slices? Go for it—they’re perfect for small smoothie portions, desserts, baking, or even topping your oatmeal.

⚠️ PSA: never use sharp knives with your trays. Silicone is incredibly tough, but not invincible. Stick to dinner or butter knives or other dull tools.

❄️ Freeze for at least 6 hours and use within 4–6 weeks for the best taste and texture.

For the Smootheeze Easy Freeze Smoothie Prep Tray:

Now onto the cube trays—aka your ticket to smoothie creativity.

Prep your ingredients by washing and chopping them as needed. Pack the trays tightly without overfilling, as some ingredients expand when frozen.
Certain fruits like berries and leafy greens often do not freeze into solid cubes. You can ensure cubes freeze as solid pieces and make them easier to remove from the trays by pressing down on the fruit with a spoon so it mashes slightly or adding a small amount of water to each cavity after filling it with berries or greens. This step ins't necessary for other ingredients.
Secure the lid and freeze for at least 6 hours. Place the lid on the tray and press firmly around the entire perimeter of the tray. Lift one corner to press out the air and secure the corner again.

Now, here’s the truly fun part—get creative!

✨ These trays help you waste less by freezing produce sitting in your fridge before it goes bad.

✨ You can buy in bulk to save money and meal prep like a smoothie wizard.

✨ Try freezing all kinds of veggies (spinach, kale, cauliflower, sweet potato, beets, carrots, and pumpkin); any fruit under the sun (go beyond the berry with a rainbow of tropical fruits, watermelon, and citrus); even freeze liquids like coffee and tea, coconut milk, or homemade concoctions like flavored creamers and immune boosters.

Once filled:

👉 Press on the lid, push out the air, and lay flat in the freezer.

They’re leak-proof, but flat is key so juices freeze evenly. Once frozen solid, store however you like—even vertically!

IT’S BLENDING TIME!

When smoothie time hits, pop out your portions and toss ‘em in the blender. Some cubes might play hard to get—just twist the tray to loosen them up, then slide them out.

Tips for Maintaining Freshness

Snap it shut: Press the lid firmly around the edges until it locks in place.
Air out: Lift a corner of the lid to press out any trapped air, then re-secure the lid.
Prevent frost: Smootheeze trays keep ingredients separated, but condensation can still lead to ice crystals. Here’s how to reduce that:
- After cleaning, let the trays dry completely, or store them in the freezer until ready for use.
- Drain and pat ingredients dry to remove excess moisture before freezing.
- Let ingredients cool in the fridge before packing them into trays.
- Pack ingredients tightly, pressing out as much air as possible before sealing.
- If you notice ice on the underside of the lid, wipe it off with a towel and quickly resecure.
- Keep the freezer at a consistent temperature, and don’t leave trays out while blending.

Some frozen condensation is normal, but following these tips will help keep your ingredients at their best for 3-4 weeks.

How to Clean Smootheeze Trays

Smootheeze trays are durable and easy to maintain.

Our trays are crafted from high-quality, platinum-cured, food-grade silicone. They’re BPA-free, and free from lead, PVC, and phthalates. With the right care, Smootheeze trays are endlessly reusable and will be part of your smoothie routine for decades.

Deep Cleaning Tips

We find that a quick hand wash with a sponge and soap is enough to get Smootheeze clean and immediately refill with new ingredients. However, over time you may notice a build-up of food odors or stains, or a build-up of soap residue if you frequently clean them in the dishwasher.

If that happens, try one of these deep cleaning methods:

Citrus Scrub: Cut a chunk of lemon or lime (with peel) and use it as a scrubber. Rub it on all surfaces and let the oils sit for 15 minutes before rinsing with hot water.
Baking Soda Paste: Mix equal parts water and baking soda to create a paste. Coat the tray and leave overnight, then scrub with a sponge and rinse with hot water.
Boiling Method: Boil the trays in a mixture of 2 parts water and 1 part white vinegar for 15-20 minutes, then rinse and let them air dry.
