Bell peppers are pretty easy to grow indoors and most seeds you can buy are self flowering. Plants typically get to be about 2 feet for a good sized pepper though they will be smaller than the larger store bought ones and are pretty difficult to kill as long as you keep the thing watered. I lucked out with finding a hydroponic garden at a thrift store prior to the pandemic and bought it to see if I could successfully grow anything before I spent the money investing in an actual garden (plus the husband didn't want me dragging dirt everywhere). Tomatoes are a similar ball game but they don't have the leniency of peppers (they can be not quite ready to pick yet only for them to be rotten the next day depending on the type). Most fruits are a labor of love because the plants have to mature for years before they actually produce fruit you can eat (traditional apple trees take roughly 10 years to mature while the dwarf varieties take about 2-4).My store was pretty good just now, with one notable exception - Completely out of normal bell peppers. Only stock available was some local organic hothouse grown ones, instead of the usual import ones. At over 2x the price of the regular, which themselves have been up 20% since this time last year. The starbucks in that location seems to be getting worse though - it was rare for them to have half their food in stock before, and the menu usually one 1-2 red stickers of sold out - now its consistently 3-4, including the seasonals, and I've just given up asking about the banana bread.
Butter is extremely easy to make because it's essentially churned cream. If you're in a pinch, put some heavy cream in a jar and add a little bit of salt, close it and shake it until butter happens. Take butter out of jar and put it in a separate container and save the liquid left over (it's buttermilk and good in biscuits and pancakes). You can also technically do this with a blender/food processor and if you stop early you'll have whipped cream. Margarine is 2 chemical compounds away from plastic, it isn't good for you.That's funny, margarine is all anyone eats here. There's legit like 20 different brands even at small grocery stores, and butter is relegated to this little shelf at the top, where it's only in sticks and people only use it for baking. I never knew it was so uncommon to use margarine in other places until I read your post and googled it.
