I haven't really cooked more than a couple times a year for the past 40+ years; DH has been the cook and would shop every couple of days. We have a tiny 18 cu.ft. fridge with a freezer door that pops open if you carelessly slam the fridge door -- so not so great for frozen food.
But now things have changed. DH is the poster child for being at risk; he pretty much checks off all the risk factor boxes, plus his lung doctor told him that because of one of the meds he takes he is likely to die if he contracts coronavirus. No, he actually said he would die. And his kidney doctor and primary care doctor told him he needs to keep taking that drug. So I won't let DH see the inside of a market until maybe this fall.
Good news: He is still doing the cooking. But the tricky part is combining a planner (me) with more of an emotional cooker.
We used to shop at Trader Joe's twice a week (together), and he used to shop at Safeway probably three times a week. He would buy bread and meat at another market every ten days or so, and go to a fourth market for fish every week or so.
My goal for the short term is to shop at Trader Joe's every two weeks and Safeway every two weeks, staggering the weeks. They each have stuff not available at the other, same with the other two stores where we buy food. I will also add that he likes to cook semi-Asian and that we have a wok burner on our stove.
First, I keep a running list of staples, and am trying to keep track of what I've seen gone at Safeway like chicken broth or chicken stock, either to pick up at Trader Joe's or buy the next time at Safeway. I'm also trying to keep track of how fast I use something so that I don't run out.
I go to the meat/poultry section first because what's available or what looks good can vary from week to week. I had to cook for a couple of weeks last month as DH was in isolation awaiting covid19 test results, and learned NOT to buy Value Packs: Too much in the way of leftovers.
Then, I see what looks good in the way of vegetables, because again, what looks good can vary from week to week. I also learned that microwave steamed veggies go bad much, much quicker than stir-fried or roasted ones.
I was thinking that I need to have the pantry stuff around to make minestrone soup to take care of the bits of veggies hanging around just before a shopping trip. DH would never do this, but I abhor waste.
Anyway, I woke up at 5 am today wondering if I needed to put vanilla on my list (no, I have plenty) and to make sure I bought aromatics like onions and shallots. Just because. I also have DH on phone standby as I shop (what type of bacon? I don't eat the stuff) and have him empty the shopping bags so he knows what I bought.
It won't be perfection, but we'll get through this.
