Try an equal amount of balsamic vinegar.
You can substitue any kind of sherry for madeira (both are fortified wines). I personally like Golden Cream.
cream cheese
No way! completely different drinks!
no you cant
Depends on the recipe.
baking pouder
No. 2 percent milk is much too thin and lacks the fat and consistency needed to substitute for sour cream in any recipe. Low-Fat Yogurt would be a better substitute for sour cream.
Baileys is a whiskey cream, not a cream sherry.
You can substitute 1 cup Mascarpone cheese with 1 cup cream cheese beaten with 1/4 cup heavy whipping cream.
Depending on the recipe, cool whip should in most cases be interchangeable with whipping cream as a lower calorie substitute. Cool whip is an imitation of whipped cream, called "whipped topping" by its manufacturers.
Wouldn't recommend it. It'll add too much moisture to the recipe.
try cream of buckwheat, or cream of rice. or grits. i would try the rice myself.
