I have a 64 page book on vinegar that I'll share here now and then, that is if I remember. Maybe I'll not delete the email notice so I won't forget.
Fruits and Vegetables
When cooking fruit on the stovetop, add a spoonful of vinegar to improve flavor.
When making mashed potatoes, add 1 tablespoon vinegar once you've used enough milk. This will help keep potatoes white. Whip them to desired consistency.
In a tomato sauce or a tomato-base soup, add 1 or 2 tablespoons vinegar just before completing the cooking process. Flavors will be enhanced.
Meat
Add zip to a pound of hamburger by adding garlic wine vinegar and 1/2 teaspoon mustard. Work these ingredients into meat before making into patties.
Improve the flavor of boiled ham by adding 1 tablespoon vinegar to cooking water.
The acid content and tangy flavor of vinegar makes it an excellent ingredient in a marinade for meat, poultry, fish, or vegetables. Vinegar can also tenderize tough cuts of meat.
More to come!

always keep vegitables in newspaper wrap.they will stay fresh longer.

Anybody want to restart this?

When cooking rice,
Use a 1cup rice : 1/2 cup water ratio.

Add a bit of salt to the rice and cook the rice with a lid covering it.
As soon as the rice gets to a boil, simply turn the heat to off or very low on your stove top. after about 15 minutes, the rice should come out fluffy and just right.

(note: this for white rice, brown rice takes longer and may have a different water ratio)

I love your ideas!!
