We recently used guanciale fat, which is pretty similar to bacon minus the smoke. We chilled it slightly, and whipped it in a kitchen aid to stiff peaks, and served it with roasted radishes and sea salt. A simple riff on a traditional italian radish and butter
Saute sweet onion and bell pepper in bacon drippings, add vinegar, water, sugar, salt. Bring to a simmer and thicken slightly with cornstarch slurry. Add chopped bacon and you are ready to go. Hard boiled egg slices, mushrooms sliced and red onion rings complete the salad. Maybe a ripe tomato wedge as well.
Heat bacon fat, add smashed garlic(or chop it if you want the garlic pieces left in) and slow simmer until just browned. Add cider vinegar to taste and serve over greens(doesn't have to be spinach, good on small kale leaves, on small beet or turnip leaves). Optional ingredients could be anything goes form the spice or herb department! Scallions are good, as are regular onions chopped...
All great recipes. I'm definitely going to have to experiment with all of these. I am currently in the process of incorporating this dressing into a "sorry, not so sorry salad" recipe for my kitchen. Thanks for the advice!
