Make Friends with Your Freezer
Don't be afraid to put the deep chill on cheeses (hard grating cheeses like cheddar thaw best), milk (to bake with), egg whites, tomato-based products (like homemade pasta sauce), broths, wine (for future cooking, not drinking), herbs, and hardy greens like kale (blanching first helps preserve quality). And, of course, leftovers. Note: If you load up on produce at the grocery store or farmers' market, freezing the surplus immediately is the best way to preserve nutrients.
