Izakaya food consists of small dishes. I mentioned other types of small dishes from different cultures such as Spanish Tapas. A relatively new restaurant, Zaytinya in Washington DC specializes in small dishes from the Eastern Mediterranean and the Middle East called Mezze (Meze and other spellings). These dishes are quite different from Japanese style Izakaya food but the ideal is the same and my wife and I really enjoy their small dishes. We usually start with some of their spreads or dips with small wonderful hot (temperature) flat bread they serve (a type of pita or pide). Hummus (it appears that there are some spelling variations since the original name حمّص is Arabic-obviously I just copied from Wikipedia-) is one of these and is very easy to make. Here I made Guacamole and Hummus, a bit of ethnic mix but work well together.
I first drain the chickpeas reserving the liquid. I then process all the ingredients plus 1/4 of the reserved liquid (or use lukewarm water) until a nice smooth paste is formed. If it is too thick add more liquid, if it is too soupy add more chickpeas. Taste and adjust salt, lemon juice and cumin to taste. I garnish with sliced black olive and extra-virgin olive oil. Any chips, pita bread, cracker will go wonderfully with these dips.
