"Hey, can you try this new recipe I found? It looks pretty easy. I don't know what's in it, but it'll be fine. We can watch the video together. I don't know how much of it you'll actually eat, though. You usually don't eat that much at my place. Just don't make a mess, okay?"
"Cooking this new recipe together could be a fun and delicious way to spend time. Plus, we can enjoy a great meal afterward."
