Frying – Name of the Process for Heating Butter to Give It a Special Aroma

I can think of at least three things that will cause chocolate to seize - which refers to when melted or melting chocolate suddenly becomes hard again:

• Using too high a heat. Double-boiler is the safest, but you can use a saucepan on very low heat.

• Sugar bloom and other impurities. You shouldn't get this with baker's chocolate, but if you use any lower-quality chocolate, this can seep into the melting chocolate and cause it to seize.

• Contact with moisture! Even a tiny amount will cause it to immediately seize, and it's difficult to recover at that point.

Sounds like you fell into traps #2 and #3 and possibly #1. I would not melt chocolate in margarine; I'd even be wary of melting it in butter, and find it strange that a recipe would call for that, because both butter and margarine contain water!

Melting chocolate in a liquid can actually help prevent seizing, but you have to use a lot of liquid and the liquid has to be completely melted before you start trying to melt the chocolate. It's better to use something like a vegetable oil which has no water content if this is what you're trying to do.

So, in summary:

• Definitely stay away from the margarine. Even if you need to use butter, make sure it's completely melted first and try to use only the fat (clarify it).

• If you can, melt the chocolate and clarify the butter separately and then whisk them together gradually afterward; not only will this help to prevent seizing, but if commenter @roux is correct and the problem isn't one of seizing, this will still help to guarantee that the chocolate melts evenly.

• Use the best quality chocolate you can find. Chipits are generally OK to melt on their own, but if they've been sweetened then this may contribute to seizing if other factors are present.

• Melt in a double-boiler or on very low heat.

Generally speaking, butter spreads have a water component to them. That's what the emulsifier is for, as it keeps the fat and water from separating.

The problem is that you can't fry/cook with it. If you place it in a pan it will separate, and sizzle in a very unpleasant manner. If I remember correctly, it actaully smells quite awful in the process.

As for baking, I think it'll be fine anywhere there needs to be fat as fat. Wherever you need fat as something to hold the structure, you had probably best not use it. Caveat emptor, as I don't bake very much at all.

Let it be aid, however, that margarine as opposed to butter spread, can be used anywhere that butter is used. It isn't as tasty, and has trans-fats. On the other hand, it has less cholesterol.
