“What‽ Another pickled onion recipe? I thought you wanted to keep things simple!”
[dropcap]Ha![/dropcap] Fairenough. I must admit that we’re getting a little pickled onion cray here atPadaek. Just afortnight ago, I shared with you the KISS pickled onion recipeand before that I sharedGrandma’s pickled onion recipe. But you know what? Pickled onions really are that delicious and we enjoy munching and savouring their intense, sharp, juicy flavours so much that Ijust had to share with you another (hopefully final) pickled onion recipe that is also super simple – but this time, it does not use vinegar.
Instead, it uses brine (salt and water solution) (plus sugar), and optional aromatics in an ancient pickling method called lacto-fermentation.
What is lacto-fermentation?
Before modern pickled onions (pickled in vinegar), onions wereonced pickled using lacto-fermentation, which is a simple process that uses nothing more than salt and water. Thisis the same method that is used to make pickled classics such as gherkins, kimchi and sauerkraut.
The processworks because of the wonderful fact that bacteria that could be harmful to us can’t tolerate much salt, but there are healthy bacteria that can. These salt tolerant ‘good’ bacteria are called ‘Lactobacillus’ – hence, ‘lacto’ inlacto-fermentation.
Lacto-fermentation works in two stages. In the first stage, while the vegetablesare in the salty solution, the harmful bacteria are killed off while the good Lactobacillus survive. Hooray! In the second stage, the Lactobacillus organisms convert lactose and other sugars present in the food into lactic acid. This process creates an acidic environment that safely preserves the vegetables and also give lacto-fermented foods their classic tangy flavour. Yum!((1))
The benefits of eating food with Lactobacillus bacteria include a healthier digestive system and speedy recovery from yeast infections. They are also supposed to have anti-inflammatory properties and be useful in preventing certain kinds of cancer. Lacto-fermented foods are considered ‘probiotic foods’ (probiotic means ‘for life’) because they help promote the growth of healthy bacteria in the intestinal tract.((2))
Lacto-fermentation is a common process also used inLao cuisine. Both‘som puck gard’ (pickled cabbage) and ‘dorng mark plum’ (pickled sour plums) are examples of lacto-fermented Lao dishes. When wewere young, we enjoyed making and eating ‘dorng mark plum’ with a spicy dipping sauce called ‘jeow mark plum’.((3)) I usuallylet my siblings do the hard work ofpickling the plums but I remember the process quite well. Basically, the freshly picked sour plums were washed and then slicedwith a knife on the sides (similar to that withKalamata olives – so that the pickling solutionwould work its magic faster). Then, they were bottled in a glass jar with a simplewater and salt solution,and left in a kitchen cupboard to pickle/ferment for several weeks.((4))
The following probiotic/lacto-fermented pickled onion recipe is an adaptation of/based on The 1910 Bottling Company’s Probiotic Pickled Onions recipeby Steve Hogwood. Thanks very much for sharing your recipe Steve! I’ve modified itslightly by adjusting the quantity/measurements of the ingredients because I used a 1.5 kg bag of picking onions. I also alteredthe picklingsolution (by adding raw sugar) and the spice mix (by adding star anise, allspice and fresh bullet chilies, and omitting coriander seeds).
I can’t wait to see how this recipe turns out. Knowing that eating lacto-fermented foods, including lacto-fermented pickled onions is good for my inner health – if this recipe turns out well, I think I might have to make it on a regular basis and experiment with other vegetables too. Watch out gherkins, capers, cabbage and pigs ears! Stay tuned for burping and tasting updates folks!((5))
