I think there are a lot of us here who bend over backwards to satisfy our dietary (or budgetary) needs (or comfort food) (or alcoholism). I was amazed to learn that some of you make all sorts of things from scratch (cheese!).
I'm in this boat as well, I guess. I've been making beer mustard, tonic water syrup, and other low carb baking goods (using coconut flour). I've considered making salt pork, and eventually bacon. On a more simple side, I've also made hummus, dill pickles, and a pho mirin that is very low carb using liquid stevia, sake, and a touch of dark rum. Wife didn't even realize it wasn't real mirin and loved it.
I guess what this comes down to is not what you can make, but where you source the ingredients. Anyone can find a good recipe online, but I've learned that finding an ingredient for a decent price can be tough. Translations can also be tough as well.
So go ahead and share some recipes, but more importantly, let us know where you shop for your ingredients and equipment. I'll share some of mine throughout the day.
I'll add the recipe tonight.
This one is easy. All you need is are mustard seeds, cider vinegar, brown sugar, honey and some spices. I haven't had any trouble finding the spices (tumeric, allspice), and I've substituted brown sugar for other dark sugars with no issues. Cider vinegar is specifically 純りんご酢 (jyunringosu) made with 100% apples- it's not りんご酢(ringosu). iHerb has good honey- and cheaper than most retail prices in Japan. iHerb also had mustard seeds, but the customs enforcement in Japan recently tightened their restrictions and can no longer be shipped. Amazon is a bit more expensive, but still within a reasonable price.
All you need is a good blender, some jars and ham or sausages. I end up giving half of it away as a good gesture to friends and co-workers. Lasts about 3 months.
