I borrowed a copy of Cooking Light: Annual Recipes 2006 from the library and I have been working my way through the tome for new ideas. There's a feature on making your own yogurt and it looks surprisingly easy so I think I'll give it a go. Here's the instructions. Does anyone have any previous experiences to share?
4 cups 1% low-fat milk (or whatever grade you want)
2 tbsp plain low-fat yogurt (or whatever grade you want, as long as it contains live and active cultures)
Place milk in a large saucepan, heat over medium/high until bubbles appear. Remove from heat. Cool until temp registers 110-112 on a thermometre. Transfer milk to a glass container and stir in yogurt. Cover tightly with plastic wrap and place in an unheated oven (gas - with pilot light on; electric - with light on) for 8 hours to overnight. Remove wrap and gently shake container to see if it is thick. If not, let sit a few hours longer. When thick, place container in fridge to chill. Makes 4 cups.
