For lunch, I'm making Thai yellow curry with tofu and vegetables.
I bought a bottle of Trader Joe's yellow Thai curry sauce and ran into my usual problem that I get when I make stir-fry, etc. The bottle says it makes 5 servings of sauce, so I pull out what I think is 4 servings worth of each vegetable. Four small potatoes, check. Half a large onion, 3 small carrots, check and check. A quarter of a small head of cabbage that's rolling around in my crisper? Check. Ooh, I even have a block of tofu!
I cook the potatoes and set them aside, then start sauteing the onions and carrots and it's all looking good. I add in the cabbage and think that this will be perfect. I stir in the tofu and add back the potatoes and, look out, my giant skillet is overflowing! Suddenly the bottle of sauce for 5 servings doesn't even begin to cover my 4. Fortunately I find most of those bottled sauces too salty, so I add enough water to cover all my vegetables.
I really need to learn that they mean 5 servings of meat, which is considerably smaller than 5 servings of vegetables, and that my definition of a serving of vegetables is probably twice as large as everybody else's. Good thing I love leftovers.
