A growing collection of small‑batch fermented sauces from my kitchen in rural Andalucía.
At Casa Adora, I’ve been experimenting with small‑batch fermented sauces that develop deeper flavour with almost no effort.
I’ve dabbled in fermenting on and off for years, but it wasn’t until the recent storms battering Andalucía that I really settled into it. Days of wild weather, dogs asleep by the fire, and jars quietly bubbling away on the counter — it all pushed me deeper into the world of small‑batch fermented sauces and homemade chilli ferments.
Everything here leans towards Casa Adora: small‑batch, sun‑driven, naturally fermented, and shaped by whatever the season brings. But at the end of the day, I’m still The Flexible Chef — experimenting, adjusting, tasting, and letting each batch find its own way.
If you’re new to fermenting, you’ll find all my notes, tips and step‑by‑step guides in the Fermentation Hub.
Below is the current line‑up of my small-batch fermented sauces I’ve made here at home, each one beginning with nothing more than chillies, salt, garlic, and time.
The joy of small‑batch fermented sauces is that you can tweak heat, sweetness, and funk without committing to litres of the stuff.

How I Make These Small‑Batch Fermented Sauces
All of these small-batch fermented sauces begin with a simple brine ferment — chillies, garlic, salt and whatever aromatics feel right for the batch. The jars sit in a quiet corner of the house, doing their thing while the weather does whatever it likes outside.

A note on fermentation time
People often say “10–14 days” as a rule of thumb, and that’s a good starting point, but the truth is far simpler:
ferments are ready when they’re ready.
The room where my jars live sits somewhere between 14–20°C, so everything moves slowly — especially during the heavy storms that recently battered Andalucía. My SUNSTRIKE HABANERO wasn’t blended until day 20, and even then it carried on gently fermenting in a cool, dark cupboard afterwards.
The other jars are still going.
They’re at three and a half weeks now and still bubbling, still brightening, still developing their own character. I don’t rush them. I just check the aroma, the colour, the tang, and let time decide.
Every batch behaves differently.
Every chilli has its own pace.
And that’s half the joy of fermenting.
More to Come
More small‑batch fermented sauces will join the collection as new chillies arrive and the seasons shift.
Once you start making small‑batch fermented sauces, you realise how bland supermarket bottles really are.
I’ll keep adding new sauces as I experiment with different chillies and seasonal ingredients.
You can follow all the new ferments, updates and experiments right here in the
