Lacto-fermented veggies are one my most served easy side dish. You prepare them ahead of time, and then they are always ready to pull out of the fridge right before dinner time. With nearly every meal, there are at least two options available to everyone for fermented vegetables. The kids always choose between pickles and sauerkraut, Luke and I go for the jalapeños.
If you like spicy, fermented jalapeños go with nearly everything. Pop one in your mouth with a bite of tender pot roast, or add them to a fresh greens salad piled high with chicken and bacon. Oh my word, I know what I want for lunch now!
We love jalapeños, but I never want to prepare anything with them, because the kids wouldn’t be able to eat it. These fermented jalapeños are the perfect solution, because Luke and I can enjoy them, while eating the same foods as the kids. We just top our dinner with a few fermented jalapeños.
They are definitely VERY spicy, but we love them!
Health benefits of fermented foods?
Eating fermented foods is eating your probiotics rather than taking a pill. Not only are you getting your boost of healthy vegetables, but since they have been fermented your already healthy vegetables now contain healthy probiotics which helps gut bacteria.
Healthy gut bacteria has been shown to help your immune system, decrease inflammation and can help decrease certain diseases. (source)
How do you tell if peppers are fermenting?
After a few days of fermentation they will begin to change color from vibrant green to a dull green. They will also start to have a tangy taste to them.
How long do fermented foods last?
Fermented foods that are properly prepared and stored in a cool dark place can last between 4-18 months, possibly longer. Look for any signs of mold, an even color throughout, and it still looks edible.
Use your nose to see if it still smells as it should and doesn’t have a bad smell. Is the texture still good and crispy, rather than mushy. You can always taste it to make sure it still tastes good.
Tips for making fermented jalapeños:
- One of the most important things you need to do when fermenting, is keeping everything submerged in the brine so bacteria can’t grow.
- Use weights to hold the peppers down, or use cabbage leave.
- Allow brine to cool a bit before pouring over the sliced jalapeños because pouring hot water could potentially kill any of the good bacteria.
- If you have any, add a little brine leftover from a previous batch as a starter to help get the good bacteria growing.
