HOW LONG IS SAUERKRAUT GOOD FOR RECIPES

Steps:

• Weigh your cabbage to see how much salt you should use.Remove the outer leaves of your cabbage and any that are damaged. Discard. Cut out the core and rinse the cabbage well, allowing the water to flow between the cabbage leaves. Drain well.Reserve 1 outer leaf. Thinly shred the remaining cabbage with a knife or food processor. Place in a large bowl. Sprinkle the calculated amount of salt over the cabbage and toss well. Let sit for 15 minutes. Massage the cabbage with your hands for 5 minutes. The cabbage should release a good amount of liquid during this time.Pack the cabbage firmly into a very clean glass quart jar. Pour the liquid that was released during kneading on top. Cut a circle the same diameter as your jar out of the reserved cabbage leaf. Place it on top of the packed-down cabbage. Place a weight on top of the cabbage to ensure that it stays under the brine. If the brine doesn't completely cover the cabbage and weight, top off with a 2% solution of salt water (1 teaspoon salt per cup of water).Screw a plastic lid onto the jar. Place the jar in a rimmed pan (to catch any overflow) and allow to ferment at room temperature until the kraut is as sour as you like it. This can take anywhere from 1–4 weeks.After it's done fermenting, store the sauerkraut in the refrigerator.

Steps:

• Drain the sauerkraut, keeping the juice (we won’t use it here, but feel free to drink it - it’s very healthy!). Have a taste - if the sauerkraut is extremely sour, it’s worth giving it a rinse under running water first, then squeeze it out.
• Roughly chop the sauerkraut, so that the strings of fermented cabbage aren't too long.
• Move the sauerkraut into a deep frying pan/skillet. 
• Pour in enough hot water to nearly cover the sauerkraut.
• Add in 2 tablespoons of butter (don’t worry, it will melt on its own), 2 bay leaves, 1 tablespoon of cumin, 5 black peppercorns and 2-3 allspice berries.
• Cover with a lid and braise until soft. Sauerkraut will become soft after around 40 to 50 minutes of cooking. Monitor the process from time to time, making sure nothing boils over or sticks to the pan. Add more water if necessary.
• [optional step: apple] After 25 minutes of braising (somewhere around the half-way mark), add an apple. Peel one small sweet apple (weighing roughly 3.5 oz / 100 g before peeling) and chop it finely. You can also grate it instead (using the largest holes). Add the apple pieces into the sauerkraut and continue braising.
• [optional step: bacon] As the braising is nearing the end, let’s fry the bacon: Chop the smoked bacon into cubes (or small pieces) and fry them up on a separate frying pan until lightly golden. Usually bacon renders enough of its own fat, so no additional cooking fat is required - but if your bacon is very lean, feel free to grease the pan with some oil. 
• Add fried bacon into the braised kraut, fold it in.
• Add chopped onions into the same frying pan (same one we used for cooking bacon). Sauté them for a few minutes until they turn translucent.
• Add 1-2 tablespoons of flour into the onions, and stir them in (with a pan-friendly spoon or a spatula). 
• Add in half a cup of water and stir continuously. Increase the heat and bring into a near-boil (keep on stirring!).
• Move the contents of the frying pan (onions + roux) into the braising sauerkraut. Stir everything together.
• Have a little taste. Does it need some more salt and pepper? If so, season it a bit more, I usually do. If it tastes a bit too acidic for your liking, add a pinch of sugar. Stir everything together and switch off the heat.
• [optional step] Chop fresh dill finely and fold it into the sauerkraut. Serve hot.
