Give anonymous canned food
When rumbling, it is customary to give the future couple something. My advice: A big box full of cans of ravioli, sauerkraut, ready meals, fruits, corn, beans, dog food and so on. Everything that can be found in round cans.
The joke here: you have to remove all labels. This is how cooking becomes a roulette game for the two of them. When it comes to animal food, however, it should be fairness to say "animal food" or something similar. Otherwise, but no indication of the content!
