Here, I've used Richard Bosman's excellent locally cured prosciutto, which is available in selected delis and other outlets in Cape Town. I know it may seem like heresy to fry prosciutto, but it is so splendidly crisp and flavoursome prepared this way that every time I taste it I want to fall into a dead faint.
You can serve these beans piping hot or at room temperature. If you're not serving them hot, don't omit the step of plunging them into iced water to set the colour.
Lemony Green Beans with Frizzled Prosciutto, Fried Breadcrumbs & Aïoli
two packs of young green beans (enough for six)
4 Tbsp (60 ml) extra virgin olive oil
the juice of a lemon
salt and milled black pepper
six slices of prosciutto
sunflower oil for frying
For the aïoli:
2 large egg yolks, at room temperature
a pinch of salt
1 tsp (5 ml) Dijon mustard
150 ml light vegetable oil (such as sunflower or canola oil, or any other flavourless oil)
170 ml good, fruity olive oil
the juice of a lemon
a large clove of fresh garlic, finely grated (or more, to taste)
freshly milled black pepper
First make the aïoli. Put the two egg yolks into a small bowl (a ceramic soup bowl is ideal) and add the salt and mustard. Mix the vegetable oil and olive oil in a small jug with a sharp pouring nozzle. Place a damp cloth underneath the soup bowl so that it doesn't skid around while you're making the mayo. Using a rotary beater (electic whisk) beat the egg yolks and salt for a minute. If you don't have such a gadget, use an ordinary wire whisk, and plenty of elbow power.
Now, as you whisk the egg yolks with one hand, pick up the jug of oil with the other, and dribble a little splash of oil onto the yolks. Keep whisking and dribbling, a little splash at a time, with great energy, and within a few minutes you will see the egg mixture begin to thicken rather dramatically. Keep adding the oil, a dribble at a time, until you have a thick yellow ointment. You may not need to add all the oil: stop adding oil once the mayonnaise has thickened to your liking. Stir in the lemon juice, garlic and pepper, and add more salt if necessary. Set aside.
Fill a bowl with cold water and add to it a handful of ice cubes. Top and tail the beans. Bring a pot of salted water to the boil and add the beans. Boil rapidly for 2-3 minutes, or until the beans are just tender. (How long you cook them will depend on the size and age of your beans.)
Drain the beans. If you're not serving this piping hot, immediately plunge them into the ice water. Leave in the water for three minutes, then drain and pat dry.
In the meantime, prepare the toppings. Heat sunflower oil, to a depth of a millimetre, in a frying pan. When hot, but not smoking, add the prosciutto slices, a few at a time, and cook for a minute or so, or until frizzled and crisp. Drain on a piece of kitchen paper. Now crumble the breadcrumbs into the hot oil and fry until crisp and golden (remember that they will carry on browning once you remove them from the heat, so don't let them get too dark). Drain on kitchen paper.
To serve, toss the beans in the olive oil and lemon juice and season with salt and pepper. Pile onto a platter (or onto individual plates) and top with the prosciutto and breadcrumbs. Serve with a large dollop of aïoli.
