i have seen measurements as chefs spoon how much is a chefs spoon ? :
It's a good question. The responses so far remind me of the phrase: "how long is a piece of string?"
For example if it really is 4 tbls, like I always assumed, but you followed Naga's advice to use 3 tbls, you'd be a whopping 25% out. Rather than risk ruining a dish by getting it 25% wrong, it might be better to check for each specific recipe. What a pain!
