There’s something special about jalapeños…
Bright, fiery, full of personality — the kind of ingredient that brings a dish to life with just one bite.
Here at Cooked from Scratch, we love taking simple produce and turning it into something extraordinary, and right now our kitchen smells of that fresh chilli heat and tangy fermenting goodness that only jalapeños can bring.
These beauties are perfect on tacos, burgers, toasties, roast meats, flatbreads, grazing boards — honestly, they end up on everything around here. And the best part? With a little salt, time, and magic, you can ferment them at home and enjoy that lively flavour for months.
🌶️ How to Make Fermented Jalapeños
A simple, delicious ferment for your kitchen
Ingredients
Fresh jalapeños – 500g
Non-iodised salt – 15g (3% brine)
Filtered water – enough to cover
2 garlic cloves, lightly crushed (optional)
A few peppercorns or coriander seeds (optional)
Method
Slice the jalapeños into rings and pack them tightly into a clean jar. Add garlic or spices if using.
Dissolve the salt in filtered water to create a 3% brine, then pour it over the jalapeños so they’re fully submerged.
Place a fermentation weight on top (or use a small clean jar) to keep them under the brine.
Loosely seal the jar so gases can escape and leave it at room temperature for 5–10 days.
Burp the jar daily or use as we have a fermentation jar that does the job for you and taste from day 5 — once they’re tangy, vibrant, and a little fizzy, move them to the fridge.
They’ll continue developing flavour and will keep for months refrigerated.
How to Use Them
Layer onto burgers and grilled sandwiches
Scatter over nachos or tacos
Chop into dips or spreads
Add to flatbread toppings
Make into a hot sauce
Fold into scrambled eggs or shakshuka
Serve with your fermented chilli sauces for a flavour duo
