Hi Avirachelli. I grew up in a frum home, but I got married knowing how to do NOTHING 😉
There are a few angles to this. There’s making something following a recipe, and juggling all the dishes to get to or stay at the right temperature for serving. You’ll get the hang of both in due time.
When you find a recipe, especially if you go online, you want something that’s gone through a test kitchen and is tried and true. (With the exception of the wonderful recipes people here are offering, I’m sure 😉
What kind of a recipe are you looking for – dessert, cake, main course, etc.?
