Fermented Red Onions
Crisp and tangy onions - perfect next to steak or BBQ
Ingredients
5 large red onions, thinly sliced
1 tbsp sea salt
1 litre filtered water
Method
Pack onions tightly into a jar.
Dissolve salt in water to make a brine.
Pour over onions to fully submerge and weigh down.
Ferment loosely covered at room temperature for 5–7 days, tasting from day 4.
Refrigerate once pleasantly tangy.
Notes
Onions must stay fully submerged to ferment safely.
Flavour mellows and sweetness develops as they ferment.
Keeps refrigerated for several weeks.
This method gives a clean, crisp, lightly sour fermented onion that works well on salads, sandwiches, and cooked dishes.
