The Ice Cube Tray Hack for Preserving Wine and Herbs
Stop pouring half-empty bottles of wine down the drain and throwing away rotting herbs. Utilize your freezer to create instant flavor bombs for future pan sauces.

The Problem with Leftovers
A recipe calls for a half cup of dry white wine to deglaze a pan. You buy a bottle, use the required amount, and leave the rest sitting on the counter. A week later, the wine has oxidized, turning into a sour, vinegary mess, and you pour $15 down the drain.
The same tragedy occurs with fresh herbs. You buy a massive bunch of thyme for a single roast chicken, and the remaining 90% of the bunch rots in the crisper drawer. These leftover ingredients are culinary gold, and wasting them is entirely preventable.
The Freezer Solution
The freezer halts the oxidation of wine and the rotting process of herbs indefinitely. By using a standard silicone ice cube tray, you can portion these leftovers into perfectly sized, ready-to-use flavor bombs.
- A standard ice cube tray holds approximately 2 tablespoons (1 ounce) of liquid per cube.
- This makes future cooking incredibly easy, as you can simply pop out two wine cubes when a recipe calls for a quarter cup of wine, without ever having to open a fresh bottle.
Step-by-Step: Preserving Wine and Broth
This method works perfectly for leftover wine, chicken stock, beef broth, or even leftover tomato paste.
- Step 1: Get a clean, silicone ice cube tray (silicone makes it much easier to pop the frozen cubes out than rigid plastic trays).
- Step 2: Carefully pour your leftover wine, stock, or heavy cream into the compartments, filling them almost to the top.
- Step 3: Carefully transfer the tray to the freezer and let it sit overnight until frozen solid.
- Step 4: Once frozen, pop the cubes out of the tray and transfer them into a heavy-duty, zip-top freezer bag. Squeeze out all the air and seal it.
- Step 5: Label the bag clearly with a sharpie (e.g., "White Wine - 2 TBSP cubes").
- Step 6: When making a risotto or a pan sauce, simply grab a few cubes from the bag and toss them directly into the hot skillet. They will melt instantly and deglaze the pan.
Step-by-Step: Preserving Fresh Herbs
You cannot simply freeze fresh herbs in water, or they will turn to mush when thawed. They must be preserved in fat.
- Step 1: Finely chop your leftover hardy herbs (like rosemary, thyme, sage, or oregano). Do not use this method for delicate herbs like basil or cilantro, which turn black when frozen.
- Step 2: Pack the chopped herbs tightly into the compartments of an ice cube tray, filling them about halfway.
- Step 3: Pour a neutral cooking oil (like light olive oil or canola oil) or melted unsalted butter over the herbs, filling the compartment to the top. Ensure the herbs are completely submerged in the fat.
- Step 4: Freeze overnight, pop the cubes out, and store them in a labeled freezer bag.
- Step 5: When you start your next soup, stew, or steak sear, simply drop a frozen herb-oil cube directly into the hot pan as your cooking fat. It will melt, instantly releasing the aroma of fresh herbs.
By utilizing your ice cube trays, you eliminate food waste entirely and ensure you always have a massive arsenal of flavor enhancers ready to deploy at a moment's notice.
