Follow the recipe exactly until you get to the cayenne pepper. Try to add it as normal, then realise the pepper is stuck to the sides of its container. Turn container upside down over food and smack. Watch gobs of pepper fall into food. Wonder idly if that is more or less than you intended to add. Figure that it doesn’t matter because you’re making a double batch anyway. Continue to cook dahl. When dahl is done, eat it rapidly with only a little rice because rice is not something you enjoy. Realize about half-way through your bowl that, probably, you added more pepper than you meant to. Continue to eat because you are hungry. Eat until your sinuses drain and your nose runs. About that time, you will develop a bad sore throat as well.
