When you’re making mayonnaise, or stirring crème anglaise, or holding a baby on your hip while working in the kitchen, you may wish you had an extra hand or two.
I learned this trick while trying to make mayonnaise in one of my first restaurant kitchens; the example you see here is me making crème patissière at home. The problem with both these recipes is that you need one hand to do the whisking, a second hand to pour the oil (for mayonnaise) or hot milk (for set custards) and a third one to hold the bowl into which you’re pouring stuff still.
So. Take a heavy saucepan and set it on a teatowel on your work surface. Line it with another teatowel. Jam the mixing bowl into the teatowel-lined saucepan so it stays put.
Now, you can pour with one hand and whisk with the other without the bowl moving around.
