I used to live in Paddington, around the corner from the mainline rail station and a quick walk from the hundreds of Lebanese restaurants on Edgware Road. We always meant to visit them more than we did, but every time we made it into one, I fell a little bit more in love with the tongue-numbing garlic sauce served with the grilled meat. Somehow it didn't have that sharp edge that hummus can have, and it goes so incredibly well with well-spiced grilled lamb or chicken.
I tried to recreate it in spirit, more than texture, because the sauce you're served in those places is much denser than this is. I use my version to marinate chicken and pork in as well, serving a fresh batch on the side. And really, the coriander is my own addition... so you're seeing how far this is from the original but trust me, it's a bbq/picnic staple in my house and once you try it you'll be shocked how good yet how simple it is.
This is a taste-as-you-go recipe, so adjust to your needs.
Edgware Road Yoghurt Sauce
200ml of plain yoghurt (I like using Greek yoghurt, but runnier kinds work too)
1 lemon, both for zest and juice
1 tsp granulated freeze-dried garlic (in London, I buy this at Whole Foods - adjust this to your taste)
3 tbsp whole cumin seeds
1 bunch fresh coriander
Sea salt to taste
1. Pour the yoghurt into a bowl and zest the lemon into it. Then juice the same lemon into the bowl as well and mix it to loosen the sauce.
2. Smash the coriander seeds and cumin seeds with a mortar and pestle until the seeds are smashed up a bit and you're smelling the heavenly scent of cumin. Dump it in the yoghurt bowl.
3. Chop the fresh coriander and add to yoghurt mixture. Taste it and see if it needs more garlic or salt.
Serve it with warm flatbread, alongside grilled meats or use it as a marinade.
It's really flexible and I add chopped cucumbers sometimes, chives, mint, finely chopped red onion. It's the lemon-cumin seed-garlic triumvirate that gives it that wonderful taste.
