To serve 6, or 3 as a main course, 1 good-sized lamb’s heart will suffice as a starter, 2 each as a main course
Choose your peas wisely and avoid oversized starchy bullets; the smaller and sweeter the better. There is a brief overlap between pea season and grelot season; in this glorious time you would be foolish not to use grelots as delicious substitutes for spring onions.
6 lamb’s hearts, butchered and marinated
(see the book for details)
8 spring onions, trimmed and cleaned
3 heads of little gem lettuce, washed and separated
2 large handfuls of freshly podded peas
A handful of pea shoots per person,
snipped at the stem
A large handful of extra fine capers,
For the mint dressing
1 large bunch of mint, picked and
80g demerara sugar
200ml malt or red wine vinegar
100ml extra virgin olive oil
Sea salt and black pepper
First make the mint dressing. Bash the mint stalks with the back of a knife and place in a small pan with the demerara sugar and vinegar. Bring to a simmer for just long enough to melt the sugar, then set aside to cool thoroughly and infuse. Once ready, finely chop the mint and strain the cold vinegar over the leaves. Whisk in the olive oil, seasoning to taste.
To cook the lamb’s hearts you will need a cast-iron griddle or barbecue. Your hearts should be room temperature, not fridge cold, and the grill should be ferociously hot. Season boldly and place the hearts on the grill, cook for a minute and a half each side, then set aside to rest. A rare heart is a challenge, so aim instead for a blushing medium within. Now season and grill the spring onions in much the same way, charring with intent.
To serve, slice the hearts into slivers about half the width of your little finger, being careful to retain the delicious juices that are exuded in the resting. Place the little gems, peas, pea shoots and capers in a large bowl, then introduce the heart, resting juices, spring onions and mint dressing. Serve with chilled red wine.
Much like the ox heart on page xxx, this salad is also a noble bun filler.
