Cooking with lacto-fermented vegetables: the right habits

A lacto-fermented vegetable isn't only a side dish: it's a cooking tool. It brings four very useful things — acidity, crunch, salt and freshness. Used well, it transforms a very simple dish. Used badly, it disappears into the background or loses what makes it interesting.

The good news: there's nothing complicated about it. A few habits are enough. At BIONIC, our products are designed to fit into everyday life, with no technical recipe — a plate, a sandwich, a salad, a bowl, some potatoes.

Reflex no. 1 — add cold

The most important thing comes down to a single idea: add the product cold, as a finishing touch. An unpasteurised lacto-fermented vegetable is at its best when it keeps its crunch and its freshness; prolonged heat softens the texture and dulls the acidity.

That doesn't mean avoiding hot dishes — quite the opposite. BIONIC works very well with them, as long as it's added at the last moment: on a plate of potatoes, beside a slow-cooked dish, on roasted vegetables, with eggs. The product can warm slightly on contact; it should not cook.

Reflex no. 2 — balance the acidity

A lacto-fermented vegetable already brings acidity. So you need to build the dish around it, rather than adding it without thinking.

In a salad, cut back on the vinegar or lemon. In a sandwich, it can replace part of the pickles or the tangy sauce. In a rich dish, it plays the role of contrast. The right move: taste the dish first, add a small amount, then adjust. It's better to start with a little — a large quantity can make the plate too sharp.

Reflex no. 3 — keep the crunch

The crunch is a signature. To preserve it: add the product at the last moment, don't stir it into a sauce for too long, don't let it heat, drain it lightly if needed — and do not rinse it. Rinsing removes part of the taste; the juice is part of the product.

Reflex no. 4 — use the brine

The brine isn't waste: it concentrates salt, acidity and flavour. You can use it in a vinaigrette, a marinade, to lift a sauce, in a potato salad or as a sandwich base. But with measure: it's salty and tangy, a few spoonfuls are enough. (When it comes to storage, you always keep the vegetables in contact with their juice — see How to store lacto-fermented vegetables.)

Three mistakes to avoid

1. Cooking them for a long time — you lose the crunch and the freshness.
2. Adding too much — a lacto-ferment is an accent, not a base. A small portion is enough.
3. Stacking acidities — vinegar, lemon, pickles and lacto-ferment together can make the dish aggressive.

Where to slip them in, in practice

These habits apply everywhere. For ready-to-use ideas for every day — a full plate, a sandwich, a bowl, an apéro, a quick meal — see our 7 simple ways to use lacto-fermented vegetables. And for the great Swiss classics (raclette, fondue, dried meat, rösti), the guide to BIONIC pairings.

When it comes to choosing: the carrot & white cabbage is the most approachable to start with, the red cabbage brings liveliness to a sandwich, the green cabbage is very versatile in a bowl. The Discovery Box lets you try all four.
