Sweet and Sour Pickled Red Onions

The 'Cebolla Encurtida' is a textbook example of pickling, where the red onion transforms not only in taste but in colour too. In the acidic bath, the onion's dark purple shade turns into a vivid, vibrant pink, whilst the vinegar takes away the raw onion's harsh pungency. This crunchy, sweet and sour accessory provides a perfect contrast to fatty meats or even a simple sandwich.

Instructions

1

Clean the onion and slice into paper-thin rings or semi-circles.

Tip: Thin slicing is key, as the acid penetrates the vegetable structure faster, losing its rawness sooner (chemical cooking).
2

In a small saucepan, boil the vinegar, water, salt and honey together until the granules are completely dissolved.

Tip: The hot liquid opens up the onion fibres, so flavours penetrate the inside almost immediately (diffusion).
3

Place the onion, garlic and pepper in the sterile jar.

Tip: Do not stuff too tightly, so the liquid can circulate around the slices.
4

Pour the hot pickling liquid over the onion, seal, and let cool at room temperature.

Tip: Watch the colour! Under the effect of heat and acid, the purple pigments change structure, giving us the characteristic magenta shade.

Recipe FAQ

How long does it keep?
Stored in the fridge, it keeps its quality for 2-3 weeks; in fact, the flavours mature truly after a few days.
Can I use other vinegar?
Yes, cider vinegar gives a softer, fruitier result, while red wine vinegar brings out deeper flavours.
