Cream with a fat content of 30 percent or more can be whipped into a foam (see Figure 25.1). One quart or liter of cream produces up to 2 quarts or liters of whipped cream.
For the best results, observe the following guidelines:
- Have cream and all equipment well chilled.
- Do not sweeten until the cream is whipped. Sugar decreases stability and makes the cream harder to whip. Use powdered sugar instead of granulated sugar for best stability.
- Do not overwhip. Stop beating when the cream forms stiff peaks. If it is whipped longer, it first becomes granular and then turns into butter and whey.
- Cream to be folded into other ingredients should be underbeaten because the action of folding it in whips it more and may overwhip it.
