Q: CONTEXT: There are a couple of things you can do to prevent sugar crystallising. You can add some glucose syrup, or you can 'invert' the sugar by adding some acid, namely cream of tartar. Both should be readily available, online if not at your supermarket. Cream of tartar is also useful when making meringue.  <sep>  Q: How can I prevent simple syrup from crystallizing? A: ou can add some glucose syrup, or you can 'invert' the sugar by adding some acid, n 

A: what sort of acid would you recommend?

Q: CONTEXT: The cause is that the mousse dries out on the surface. It builds a skin of dehydrated mousse. It happens with most cremes, not only your yolk foam. To prevent it, put plastic wrap on the mousse. Don't span it over the bowl, press it on the surface itself, without leaving air between the mousse and wrap. Your mousse will stay soft. This also works for custards and starch-thickened puddings. In general, also cover other things you put in the fridge, or they can get an unpleasant odour.  <sep>  Q: Why is there a rubber like skin on surface of my chocolate mousse? A: The cause is that the mousse dries out on the surface. It builds a skin of dehydrated mousse. It happens with most cremes  Q: Is there a way to prevent it? A: put plastic wrap on the mousse. Don't span it over the bowl, press it on the surface itself, without leaving air between the mousse and wrap. Your mousse will stay soft 

A: Is it harmful to have the rubber surface?

Q: CONTEXT: The key difference from my perspective is cleaning. Silicone is the easiest material in my kitchen to scrub clean, with the possible exception of stainless steel. Cloth is very far down the list.Also, depending on the texture of the cloth, more food will almost certainly stick to the cloth, unless it's sealed with something, in which case what is it sealed with? And how is it sealing the fiberglass in?I use the kind with a thin grid of fibers inside the silicone. It adds more stability and lets the overall thickness be thinner for better heat transmission, compared to a plain silicone silpat. As long as I don't use it as a cutting board, the fiberglass stays safely inside. It does add a very slight grid texture to the bottom of loaves, but it's barely noticeable and doesn't look bad at all.The pyramid kind, which would reduce food contact and increase drainage and airflow, sounds like it would be good for specific applications, but not something I'd make a batch of cookies on.  <sep>  Q: What are the differences between cloth, fiberglass and silicone baking mats? A: Silicone is the easiest material in my kitchen to scrub clean, with the possible exception of stainless steel. Cloth is very far down the list 

A:
What would you use the cloth one for?
