That's interesting - another large gap in education?
For me, it was a matter of starting small. When I got my own apartment, I started out semi-cooking for myself: I would buy the pasta, buy the sauce, and then just pour the sauce over the pasta. Same with salad, etc. Only since lockdown have I started making sauce, pastries, and even jam for myself. Cooking with pre-made ingredients like that is still better than not cooking at all, and it's potentially a starting point from which to slowly start making more things from scratch.
