To celebrate Earth Day (4/22) this months Recipe Redux is looking for ways to reduce food waste.

One great way to reduce food waste is to compost, which transforms organic waste into a nutrient rich soil. This can be done in your own backyard or through community composting opportunities. I’ve been holding onto weekly food scraps and dropping them off at my local farmers market for a while now. 

But, a growing collection of veggie scraps has me thinking…could there be another use for them before their exit from the kitchen? 

Enter, the scrap broth.

Saving food scraps

The next time you’re preparing dinner, consider keeping the top/bottom/skin from your vegetables—whatever you would normally trash—to turn into a vegetable broth. Be sure that the veggies you’re saving are clean (wash them first) and discard anything that may have gone bad or still looks dirty.

Collect the scraps in a resealable container stored in the freezer. Once full, these “kitchen scraps” combined with water transform into a flavorful vegetable broth. Save as much or as little as you wish before re-purposing the scraps.

Ways to use the scraps broth

Once you have this flavorful broth, it can be used in a number of different ways.

Soup & stews

Most obvious would have to be in homemade soups.

Cooking liquid

Use in place of water. Either in a recipe when water is added (sauces) or when foods are steamed or boiled in it (vegetables, grains or beans).

Baking

It can even be used in baking, as the liquid in homemade bread & dough, like these spiral onion rolls.
