Not all peppers are born equal. There is this general assumption that peppers, underneath the colour of their skin, are all basically the same. Nope. That’s humans you’re thinking of. The various colours of peppers greatly affect not only their flavour, but (as far as I’m concerned) how and with what you should cook them.
For starters, chilli peppers (which we can cheerily take to cover everything from jalapeños to Scotch bonnets) should not be cooked. This is another of this instances where I share my heretical beliefs about some of the most worshipped vegetables on the planet: I think chilli is horrible. If the brutality with which it attacks lips, mouths and digestive systems wasn’t enough, their actual flavour – aside from the heat sensation and sweetness – is surprisingly insipid. This could be due to the fact that chilli quickly bludgeons your taste buds to early death before you’ve chewed it twice, but it comes to the same thing: flavourlessness. Avoid. Use black pepper instead.
Bell peppers in the UK are generally sold simply as ‘peppers’, and unlike their tightly-packed chilli cousins, release their seeds like an exploding lily anther whenever you try to cut them open. They also beg the most terrifying question in all vegetation: if they’re not flesh throughout, if they’re hollow, what gas was inside the pepper before I cut it open? Was it a vacuum? Did it contain argon? Is it like releasing a capsicum fart? What is inside those things?
Outside, bell peppers can be anywhere between Amsterdam red and Slytherin green, with all the in-between levels of fun which that suggests. Green peppers are almost prohibitively bitter, and don’t take kindly to crude treatment – or rather, crudité treatment (PUN!) That doesn’t mean they’re useless, however, because they can give overly sweet tomato sauces or curries a rehabilitative maturity. Just don’t invite them on a picnic.
Yellow peppers are the wateriest and least interesting – in fact, despite the green’s bitterness, I would say yellow are the least appetising, because they are neither particularly bitter nor particularly sweet. I suppose this makes them useful in smoothies and soups because they add 1 of your 5-a-day without upsetting the flavour balance, but all the same…
Red peppers are the fruitiest and most tomato-like in flavour, and can be used in all applications. Orange peppers, on the other hand, need TLC. Orange is my favourite colour so it’s unpredictable that orange is my favourite pepper, but as far as I’m concerned, cooking orange peppers diminishes the almost perfumey piquancy of them; orange peppers have a floral, exotic-fruit tang to them, so I like to eat them raw whenever possible. They’re also so beautiful: why would you ever want to scupper that day-brightening sunburst by braising? And why would you want to do so when you can make a rainbow-coloured couscous salad?
Rainbow couscous salad – Hurrah!
- Cook 80g wholegrain couscous according to your packet instructions. This usually involves soaking in twice the volume of boiling water for 5-10 minutes. As ever, non-wholegrain couscous is a waste of time and money.
- Now the fun bit! Dice, into equal-sized pieces, 1 orange pepper, a handful (about 7) purple radishes (usually labelled as ‘speciality’), 10cm cucumber and a handful (about 8) cherry tomatoes. For those keeping count, that’s four of the seven rainbow colours.
- Once the couscous is cooked, add the diced vegetables plus about 6 heaped tbsp cooked sweetcorn – canned is fine. Dress the couscous with extra virgin olive oil and a dash of posh vinegar or citrus juice of choice – start with a tbsp each and then taste to see if you want more. Avocado oil and lime juice would be good.
- As you can see, my rainbow couscous only caters to five colours: red tomatoes, orange pepper, yellow corn, green cucumber and indigo radishes (they get bluer upon sitting in the couscous). If your prerogative is colour over taste, then I suggest: for the blue, steamed and shredded red cabbage (which is blue), blueberries or sage; for the violet, beetroot or red kidney beans. Blue and violet vegetables will not be spot-on here, but whimsy finds a way.
