Coffee overcooked: Add a pinch of salt
Dough is lumpy: Add more liquid and pound the dough thoroughly.
Dough won't rise: Put the bowl of dough in a warmer place - in an oven, for instance, with a pilot light (do not turn the oven on). You could also mix a bit more yeast in ¼-cup warm water and knead into dough.

Scummy stock: Add leek tops and tomato peels, which absorb the scum.

Vegetable old: To pep them up, add a pinch or two of sugar and a little salt to the cooking water.
Vegetables overcooked: Puree them. Or make a cream soup of them Or put them in an oven-safe dish, cover them with bread crumbs and grated Parmesan cheese, and broil for a couple of minutes.
Vegetables too salty: Pour the water out, rinse them off, and return them to the stove in new water. If you are already done, wash in hot water.
Whipping cream won't whip: chill everything (bowl, cream, beaters) and try again. If that fails, add an unbeaten egg white or 3-4 drops of lemon juice and whip as hard as you can.
