I grew up with kraut…my grammy used to make it all the time. While I’ve made it myself, I just don’t like the fragrance wafting through the house all the time. 😅. So I buy fresh refrigerated sauerkraut at grocery store. Once open, I put it into a glass quart jar in the fridge. Keeps the odor from gracing everything else. LOL.
If you don’t like it plain, try adding a tablespoon of kraut as a condiment on a sandwich or added on top of a lettuce salad.
One of my favorite brands, that I seem to find wherever we travel in the US, is Cleveland Kraut. Usually found in the produce area or health food sections in a cooler case. Though I have found certain brands nestled in a meat case.

A suggestion for kimchi if you’re not used to it, would be starting with a less spicy variety. It will say on the front of the package or bottle. Again, you can use it on sandwiches, baked potatoes, salads…
They are both super healthy foods for gut health! Let me know if you try them!
