Cut the vegetables into two-bite portions
Mix 3 table spoons of mentsuyu with 100 ml of water. This will be used later to pour over the vegetables.
Heat oil in a large pot over medium heat, add enough oil be roughly around an inch deep (enough so that the vegetables won't be touching the bottom)
Once the oil reaches 170℃ (340℉) then carefully place the vegetables one by one, making sure each piece has some space. You won't be able to fit all of the vegetables at once.
Fry until the vegetables show golden brown or looks cooked through.
Remove and drain on a paper towel.
Repeat until all the vegetables are fried.
Once all vegetables are fried, place them in a shallow bowl and pour over the mentsuyu you made in step 2.
Serve! Tip: If you have some time to wait, chilling the vegetables in the fridge for a couple hours help soak the flavours into the vegetables. It's also delicious served cold!
