The ultimate steak sandwich

Every now and then you just nail something. Today I nailed a steak sandwich. The steak was perfectly cooked, the onion was deliciously caramelised, the bread was soft and fresh and best of all - the homemade balsamic aioli.

I think this was originally a Bill Granger recipe, but I've added my own twist, of course :)

Today I also discovered how easy it is to make home made aioli and mayonnaise using our new mini food processor. I don't think I'll ever buy mayo again.

Ingredients:

3 tablespoons olive oil
1 very finely sliced onion
2 tablespoons balsamic vinegar
Salt
Pepper
4 slices of porterhouse or sirloin steak
8 slices of fresh bread, ciabatta or something along those lines
A couple of handful of rocket, washed and dried
8 slices of cheese
Tomato relish
Balsamic aioli - see recipe below

Balsamic Aioli
2 egg yolks
1 tablespoon balsamic vinegar
2 garlic gloves
salt
pepper
1 cup oil - olive or canola

Instructions:

Steak Sandwich
1. Heat 2 tablespoons of the olive oil in a large frying pan over medium heat, add the onion and cook for 10 minutes, stirring frequently, until golden.
2. Add vinegar, salt and pepper and cook for another 10 minutes until caramelised.
3. Remove onion from the pan and set aside.
4. Using the same pan, heat the remaining olive oil over high heat.
5. Add steak to the pan and sprinkle with salt and pepper.
6. Cook steak to your preference
7. Spread one piece of the bread with aioli and the other with tomato relish
8. Put the steak on the aioli, top with caramelised onion and cheese. Place rocket on top.
9. Top with a second slice of bread.

Balsamic Aioli
1. Place egg yolks, vinegar, garlic, salt and pepper in a mini food processor and whisk until combined.
2. Add the oil drop by drop, whisking constantly.
3. When the sauce starts to thicken, add the oil in a steady stream until the oil is fully incorporated.

Enjoy!
