There is almost nothing that can surpass a perfectly rendered steak sanga, it is a thing of beauty. The messier the better, chin dripping, finger-licking, oozy, delicious layers of flavour. This summer we are giving flank or skirt steak a go, not only are they super tasty there’s the built-in bonus of being more cost-effective than other cuts of beef.

1. To make the steak sandwiches
The steaks need to be served medium rare (medium at most) and respond well to a hot fast griddle with a decent rest. Season both sides of the steak generously with sea salt, put the steak directly on a hot griddle (or cast-iron pan), lightly weight the steak and cook for 1-2 minutes before turning for another minute or 2. Towards the end of the cook add the olive oil, turning the steak to coat, making sure you have a golden crust. Remove from the heat and rest for 10 minutes.
While your steak is resting, butter both sides of the bread and grill until golden.
2. To make the chimichurri
This can be prepared in advance; the flavours benefit from some sitting time. To play with the flavour profile you could substitute the fresh chilli for roasted or fermented chilli. Traditionally the ingredients are hand-cut cut but this can also be prepared in a food processor.
3. To make the caramelised onions
Heat the oil in a medium saucepan or frying pan, over medium heat, add the onions, mustard seeds, brown sugar, sea salt and a good grind of black pepper. Sauté for 5 minutes until the onions soften, reduce heat to low and cook gently, taking care not to brown until dark and jammy. Add a little water if the pan becomes dry. These can be made in advance and stored in the fridge for 2-3 days, heat before serving.
4. To make the aioli
Using a whisk, electric beaters or a small food processor, whisk/beat/blitz the egg yolks with the salt and garlic. With a continuous motion (whisk/beat/blitz) gradually add the oil in a very thin steady stream, pausing the oil occasionally to allow the aioli to emulsify. Stir through the lemon juice and season to taste. Refrigerate until needed.
5. To make the garlic butter
Mix the butter, garlic and salt. Refrigerate until needed, bring to room temperature before using.
6. To make the potato straws
Wash and peel potatoes then julienne using a mandolin. Transfer the julienned potato into a bowl of iced salted water (for a minimum of 30 minutes). Drain, dry and store in a lidded container lined with paper towel.
While your steak is resting, heat the deep fryer (or large saucepan with 10cm oil) to 180°C. Cook (about a handful of straws per sandwich) until crisp and golden, drain and season. It’s important to note that these need to be cooked to order and prepped on the day of use.
7. To assemble
Thinly slice the steak across the grain, spread the grilled bread with any sauces and top with the fillings, finishing with the sliced steak. Serve immediately with some potato chips or fries on the side.
Note: Flank and skirt are best cut to 400-600g pieces over individual steaks. The time will vary slightly according to the thickness. Meat weights are beneficial for cooking these steaks.
