Pea Risotto

Recipe from Kew on a Plate with Raymond Blanc.

Fresh, sweet peas combined with the luxurious fat grain of the rice makes for an exceptional spring dish, with just enough heartiness if the weather isn’t yet that warm. The variety of pea I chose for this dish was Feltham First, which is a long-standing British favourite – a low-growing, early variety that produces lovely sweet, but not too sweet, peas. Rather than using a chicken or vegetable stock, I wanted to try making it just with the pea pods to intensify the flavour – and also because I never forget my mother’s mantra, ‘thou shalt not waste’!

But during this process I discovered something very interesting. The first time I made the stock I chopped and puréed the raw pods and then added water – but the taste, oh it was horrible – soapy and bitter! Intuitively I thought it must be enzymes within the flavour compound, so I tried again and this time I blanched my pea pods in boiling water for about 40 seconds, hoping to remove the bitterness. I cooled them down, chopped and puréed them, then I made my stock. And it worked like a dream; it had a beautiful clean pea flavour.

Yet, I wanted to know exactly why this chemical reaction had happened. I contacted a wonderful scientist friend, George Oakland, who did some research and discovered that the culprit was the flavour/aroma compound, pyrazine. It is also found in some wines, such as Sauvignon Blanc and some Bordeaux. Pea pods contain quite a lot of pyrazine and its harsh, raw vegetal flavour was coming through in the cooking process. By blanching the raw pods for just 40 seconds, you neutralise the compounds. I still find it so fascinating and extraordinary that one small process can change the flavour so completely.

Ingredients Required

For the pea stock (makes 600ml)
350g Fresh pea pods, shelled (use the shells for the stock and the peas for the purée and vegetables)
350ml Iced water
For the pea purée
100g Fresh peas (shelled weight)
10g Unsalted butter
1 pinch Sea salt
For the risotto
1/2 White onion, diced
2 tbsp Refined olive oil or 30g unsalted butter
1 Small garlic clove, finely grated
200g Carnaroli rice
100ml White wine, plus extra to finish (optional)
40g Freshly grated Parmesan
1 pinch Sea salt and freshly ground black pepper
For the vegetables
5g Unsalted butter
120g Baby courgettes, cut into 2mm slices
140g Fresh peas (podded weight)
40g French breakfast radish, sliced
40g Radish tops
40g Baby leaf spinach
To finish
1/4 Lemon juice
50ml Extra virgin olive oil or 50g unsalted butter
To garnish (optional)
15g Pea shoots, blanched in boiling water for 5 seconds
20g Parmesan shavings

Cooking Method

Start by making the pea stock, in a large pan of simmering water, blanch the pea pod shells for 1 minute. Using a slotted spoon, remove the blanched shells and refresh them in the iced water. (By refreshing the pods in the iced water you not only retain the colour but also the freshness and maximise the retention of vitamins and nutrients.)

Once cooled, blitz the iced water and blanched pea pods in a food processor until smooth and strain through a fine sieve. Set aside 100ml to make the pea purée and the remaining 500ml to make the risotto.

Next, make the pea purée. In a small saucepan on a medium heat, sweat the peas in the butter for 5 minutes, adding a pinch of salt. Add the 100ml of reserved pea stock, bring to a boil and simmer for 4 minutes. Transfer to a blender or food processor, blend until smooth and leave to cool.

For the risotto

In a medium saucepan on a low heat, sweat the onion in the olive oil with a pinch of salt for 2 minutes, until translucent. Add the garlic. Stir in the rice and continue to cook on a low heat for 3 minutes, until the grains of rice appear shiny (this will give flavour and prevent them sticking together).

Pour in the white wine, then the 500ml of reserved pea stock, stir and bring to the gentlest simmer with only one bubble breaking the surface every minute. Season with salt and pepper then cover with a lid and leave to cook for 20 minutes. Check every now and again that it is not boiling.

After 20 minutes of cooking, pick up a grain of rice. You will see a tiny speck of white starch in the middle – this means the risotto is nearly cooked. Now you need to add the creaminess that we love so much in a risotto and that means 5 minutes of hard and fast stirring. By beating the rice, each grain will rub against another, which will extract the starch and give the rice its beautifully creamy consistency. Stir in 200ml of the cooled pea purée, which will revive the colour and add freshness. Stir in the Parmesan, taste and correct the seasoning. Set aside.

Prepare the vegetables

In a small saucepan on a high heat, bring the butter, 50ml of water and a pinch of salt to the boil. Add the courgettes, cover with a lid and cook on a high heat for 30 seconds, then add the peas, radishes, radish tops and spinach, cover again and continue for 20 seconds.

To finish the risotto, stir in the lemon juice, olive oil or butter and maybe a dash of white wine to sharpen the flavour. Taste and adjust the seasoning. You can serve the risotto in a large dish topped with the vegetables, blanched pea shoots and a few shavings of Parmesan, if using, or in four large bowls.
