Why it works: Pepper and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 27,814 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Slovenian Ajvar
Ingredients
Directions
Prepare the vegetables
Grill halves of the peppers until the skin is blackened.
Cut the aubergines in half, pick them with a fork to prevent them from exploding, and grill them.
Place the grilled vegetables in a bowl while still hot and cover.
Leave them to steam.
Remove the skin from the peppers and peel the aubergines from stem to bottom.
Deseed and finely chop the chillies.
Make the ajvar
Mince the vegetables in a meat mincer or food processor, ensuring they are not too smooth.
Put the minced vegetables into a thick-bottomed pan, slowly stir in the oil and salt.
Bring to a boil and let it simmer gently for at least 1–2 hours, stirring until a smooth consistency is achieved and the oil forms small spots on the surface.
Add the vinegar and check the seasoning.
Allow to cool down and enjoy.

What each ingredient does
- Aubergines
- Their flesh breaks down during simmering, giving the ajvar its thick, spreadable body.
- Red peppers
- Their sweet flesh forms the base of the spread and gives it its main colour and flavour.
- Oil
- Adds richness and a silky texture, and separates into droplets on the surface as the mixture cooks.
- Vinegar
- Adds acidity that brightens the flavour and balances the sweetness of the peppers.
The step that matters
Simmering the mixture. The long, gentle simmer drives off water and lets the vegetables and oil emulsify into a smooth, thick spread. Too little time leaves it watery, while too much heat can scorch the bottom of the pan.
