Here are three that I've used lately:
Quick fix buttermilk: When you need buttermilk for a recipe, you can add a little vinegar to milk. Let it sit for 5 minutes and it becomes a good substitute:
- Add a tablespoon of vinegar to a measuring cup.
- Add milk to the same cup to bring the liquid to 1 cup.
- Let it sit for about 5 minutes at room temperature. It might get a curdled look to it but that's okay!
- Stir it up and add it to your recipe!
- Add a cup of granulated sugar to your blender (1 cup of granulated for each cup of powdered).
- Add a tablespoon of cornstarch for each up.
- Pulse it and blend it and you can magically watch your crystals become powder!
Evaporated milk makes a great substitute for milk and you can get it lowfat too! I ended up buying evaporated milk when a recipe called for sweetened condensed milk and it has been sitting in my pantry for a while. This was a great way to use it and not let it go to waste! I've also heard that the sweetened condensed milk is a great substitute too if you like your coffee sweet!
I tried to have my boys use it for cereal but apparently it's not the same in cereal. They said it tasted funny. Eh, it was worth a try!
