You do you, but those are not difficult to make IMHO. I make a ton of batter and keep it in a squeeze bottle so I can easily make my kid pancakes in the morning
For me it's macarons and most baked goods
I still make lasagna from scratch but that's because I have to use gluten free pasta. All the pre made versions are awful
Significantly? One is thick and fluffy due to a couple of extra ingredients and one is thin and light. They're basically the same thing base ingredients, prep and cooking method wise.
Macarons are one I picked up a few years back. I'd be damned if I'm paying almost $3 for a cookie after my niece asked for some at the store. I went home, compared recipes and had a few dozen in front of her that night. They're time consuming, but much of the time is waiting for them to set, which is perfect for my ADHD ass cause I just forget about them for 30 mins to a couple hours. It's a skill that has definitely paid off, and I love giving them to everyone who has never tried one because of the price.
