Cabinets just get filled with stuff. If you have empty cabinets you buy more stuff to fill them. Empty space is a vacuum, a money vacuum!
Actually, I cook a very wide range of foods because my husband is allergic to corn (maize.) No high fructose corn syrup, maltodextrin, dextrin, modified food starch, etc. I also have Meniere's disease so I tend to fall down and go boom a lot. If he eats maize, it is a trip to the emergency room and it is not good. He can swell and wheeze. This is very not good.
I have a breadmaker. I have a tortilla press. I have a regular rice cooker, a steamer, and a Persian rice cooker (to put the nice crust on it.)
I have a deep fryer, an ice cream maker, a Bethany grill (for Lefse, injera, enormous omelets, etc.) I also have a food dryer, a pressure canner, a Mongolian hotpot, a tempura pot, an apple peeler and corer, an indoor grill, a mixer, a food processor, and a blender. My husband has a coffeemaker that also makes espresso and a milkshake mixer.
Sometimes I can find Featherlite baking poweder; other times I have to make my own. Most baking powders have cornstarch. I have bins stacked up to hold Bastmati and white rice, all purpose and baking flour. I keep brown rice and whole wheat flour in the freezer right alongside a pound of SAF blue yeast and an additional pound of SAF gold yeast, the kind used for high sugar doughs.
If he wants doughnuts, I make them from scratch because the ones in the bakery can make him seriously ill. Ditto for cakes,cookies most yeast breads, most prepared foods, most restaurant meals, etc. If he wants Indian food, I make it. If he wants Persian, Turkish, Afghan, Mediterranean, Chinese, French, Japanese, Mexican, German, Philippine, or whatever food - I make it. From scratch, with maybe a few frozen or canned incgredients if I can find any that are safe for him to eat. I have bookcase that is 6 feet high and rather wide just to hold cookbooks - all carefully arranged by either methodology or cuisine. I have tagines, bread cloches for use in the oven, and special pans to provide him with his much desired hamburger and hot dog buns. I also have noodle making attachments for my mixer to make ravioli and other stuffed pastas from scratch since there are few commercial stuffed pastas that he can eat safely.
My empty space didn't fill itself - I wound up having to create more empty space so I could fulfill my husband's culinary desires.
