Measure out 1 tbsp mirin in a heatproof bowl and microwave uncovered for 50 seconds at 500W. (If you increase the recipe, the time will need to be increased.)
Add 4 tbsp ponzu sauce, 1 tsp ground sesame seeds and 1 tsp wasabi paste and whisk until evenly dispersed. Then slowly pour in ½ tbsp olive oil and ½ tbsp toasted sesame oil while whisking vigorously until emulsified.
Serve immediately, or store in the fridge and whisk right before pouring. Enjoy!
Notes
Store-bought ponzu often contains fish-based dashi ingredients not suitable for vegetarians. Check out my homemade ponzu recipe if you want to try making your own plant-based ponzu!
If making a larger batch, you can boil the mirin in a saucepan for 30 seconds instead.
I recommend using a milk frother for stable emulsifying.
You can also make this recipe by shaking the ingredients together in a dressing shaker or sealed mason jar.
