Egg + butter sauces are indeed wonderful. I love bearnaise sauce, with the added tang of the vinegar, pepper and shallots

Also, agree with the previous poster that it's very therapeutic to make it whisking over hot water, just something lovely about that. I probably make a batch of the stuff every couple weeks. Heart disease may run in my family, but what a wonderful way to go...

Also, I make salt pork baked beans from scratch from time to time. Not hard, but definitely requires patience (at least two days of slow cooking).
