A warm, savory dashi dipping sauce with soy and mirin for dunking tempura.
3 steps, about 7 minutes start to finish.
Combine dashi, soy sauce, mirin, and sugar in a small saucepan.
Bring to a simmer and cook for 2 minutes until sugar dissolves.
Serve warm alongside tempura with grated daikon and ginger on the side for mixing in.
“Keep it at a gentle simmer just long enough to dissolve the sugar, with no need to boil it down. Serve it warm and let everyone stir in their own grated daikon and ginger so those stay fresh.”
