I made the tahini sauce today so I can tell you a bit more. You start by dismantling an entire head of garlic and dropping the cloves with the paper husk into a blender. Then you squeeze THREE lemons, about 3/4 cup of lemon juice, and add that to the blender. Put in 1/2 tsp of salt and blend. AFTER blending you must leave the mixture in the blender for at least 10 minutes. There is some kind of reaction between the lemon juice and the garlic that makes the garlic flavor surprisingly mild and smooth. Then pour the mix into a fine strainer and push to get all of the juice out.
Then you need 2 cups of tahini. I had an 11 ounce jar of the very fine Soom tahini, and I didn't want to open 2 jars, that stuff is expensive, so I opened a new can of Joyva tahini and spent 15-20 minutes stirring the hard cake at the bottom into the oil. When I was done -- there didn't seem to be an enormous difference between the Joyva tahini and the Soom tahini, although the Soom had a richer flavor. At any rate I had 2 cups of combined tahini. You get a large mixing bowl (it should be larger than you think you need) with the lemon/garlic juice in it -- add 1/2 teaspoon of ground cumin and 1 more tsp of salt, and then gradually stir in the tahini. It will harden and "seize" and when that happens you have to whisk in some ice water. Eventually you want maybe 1 1/2 cups of ice water.
The result is a sauce with a great tahini flavor but a texture and body a little reminiscent of home made mayonnaise.
Solomonov says that the tahini sauce will keep for a week or so in the refrigerator. He also says that the hummus should be served fresh, and does not talk about refrigerator time for the hummus. So I stopped there.
Louise didn't measure the dry chickpeas (
) before she soaked them Monday night and cooked them yesterday but she estimates that it amounted to about a cup and a half. She thinks the cooked chickpeas will be OK in the fridge for 2-3 days so probably we will make the hummus on Saturday which is the day of the meal. The ratio is 1 cup (dry) chickpeas to 1 1/2 cups of sauce. And you simply combine those with a little more salt (1 tsp) and cumin (1/4 tsp) and whiz in a food processor -- for longer than you think is really necessary. When you serve you can top with a little more tahini sauce, some paprika and chopped parsley. Drizzle with oil. And, I think, there you have it!
My friend Susan made this with only "store bought" tahini and wrote me raving about the result, so I have high hopes.
