What’s the difference between green, yellow and red capsicums? It’s more than what you see

the gist

Red, yellow, orange and green capsicums are the same fruit at different stages of ripeness. Every capsicum starts green because chlorophyll, the pigment used for photosynthesis, dominates. As it ripens, chlorophyll breaks down and carotenoids, yellow and red pigments, become visible. Green capsicums are picked around eight weeks after planting and are firmer and slightly bitter, while red ones stay on the plant about four weeks longer and become sweeter and softer. The shape of the bumps on the bottom does not indicate sex or sweetness, since fruit does not have male and female parts in the way flowers do.

so what

Colour is a shortcut to flavour and nutrition: red peppers carry more of certain carotenoids, while the yellow and green varieties provide lutein and zeaxanthin, which support eye health. Knowing the ripening process helps choose the right pepper for raw salads or slow roasting.

fun fact

Botanically, capsicums are berries, because they develop from a flower and contain seeds.
