I fry fish in bacon grease - its amazing. You have to try it. I normally just cooked veggies and eggs in bacon grease and one day tried fish because I was out of coconut oil. It was my favorite, like luckybastard said it doesn't give it a bacon taste just brings out the flavor more.
Also, add some warm bacon grease in mashed cauliflower and it gives it more of a mashed potatoes taste and texture!
I store my bacon grease in a pyrex glass container with a rubber seal tight lid and I keep it in the fridge just because I'm paranoid.
I've seen it used in homemade mayo; I haven't tried that yet, but it sounds good to me! I like to use it in dressing for spinach salad- warm bacon grease, a little apple cider vinegar, & some good mustard. Pouring it over veggies & roasting is great too!
I've read you should strain the meaty bits to keep from going rancid, but I tend to use it up pretty quickly, so I don't bother with it.
I've always worried a little about the omega-6 in pork fat. It turns out it isn't all that bad. 1 oz. of bacon grease (~2 TBSP) has about 2.5 grams of omega-6. Not great, but not nearly as bad as I would have thought. I think that is about the same amount as in half an avocado and less than the amount in an ounce of almonds? http://nutritiondata.self.com/facts/pork-products/7358/2
im in love with any vegetable sauteed or roasted in bacon fat. especially broccoli rabe, kale, asparagus and brussels sprouts. after i make bacon, i just pour the fat into a mason jar, leave it on the counter until it cools a bit, then stick it in the fridge. no clue how long it will be good for since i use it up pretty quickly.
If I don't leave it the pan to cook the next meal in, I just pour it into a heatproof custard cup and leave it out on the counter--I go through it pretty quick. This doesn't work if you have bacon fat-loving cats though. I'm pretty casual about the whole germ thing, but tongue prints in the bacon fat is a big turnoff. Mice like it too, so if your cats don't keep the rodent population under control, definitely refrigerate.
i've started cooking everything in it. adds more flavor to whatever i cook it with but it's not a "bacon" flavor, more like it brings out the flavor of whatever i'm cooking more. lately i've been even preferring it more than the coconut oil.
Mine is in a glass jar with a tightly sealed lid, I actually leave it out on the counter. I don't store it in the fridge. That honestly never occurred to me.
I cook my veggies in it, my current favorite is a zucchini or squash cut in circles and just pan fried until golden brown. I also love to cook my eggs in it. I haven't started cooking my meat in it yet, mostly because I don't think my husband would get it. He likes his meat broiled most of the time. When I cook just for myself though, I always use the bacon fat.
I do store my bacon grease in the fridge, but only because I'm a bit paranoid. If I fill up a whole tub (rare, since I use it often), I stick the full one in the freezer and start a new one in the fridge. Supposedly it's shelf stable, though, for at least a few months.
I make my bacon in a cast iron skillet, and often I'll pour off the excess grease into a container, but not clean out the skillet. What's left is awesome for searing steaks and pork chops.
