Got hooked on this stuff in Tokyo. Great "entry drug" to eating steamed broccoli or other veggies for breakfast. Gotta watch out though- the commercial brands all seem to include MSG... so make your own!
Blend in high speed blender (or pound for a while in a Japanese mortar and pestle called a suribachi):
3 ounces (85 grams) white sesame seeds
1/2 to 3/4 cup dashi (or 3/4 water + 1 TB light miso)
3 TB reduced sodium soy sauce
2 TB mirin
1 large medjool date
2 TB sake
If you're having trouble getting the sesame seeds to break down, you can use Japanese "sesame paste" instead (but it's usually pricy). Don't use tahini as it has a totally different flavor from the Japanese kind.
Serve over salads, or over steamed broccoli & asparagus for breakfast!
