Hi. i need to make creme brulee for 5. I have the 1/2 cup dishes. But every recipe I find is for 4. It can be halved for 2, which is what I've done and it turns out beautifully. But next week I need to make 5 dishes. I really don't want to make 6 and just toss out 1/2 cup. Can the recipe for 4 be stretched a little to make 5? I was thinking of adding another 1/3 cup milk and one egg yolk, would that work? This is the Grand Marnier creme brulee. Thanks.
