Put the chicken and all the ingredients up to the soy sauce and honey in a bowl and rub in well with your hands. Leave to marinate for 30 minutes.
After 30 minutes, wipe the excess moisture off the chicken pieces and add 1 tablespoon of cake flour. That way the batter will stick well to the chicken.
To make the batter: Put the panko in a resealable bag and crush into a fine powder by rolling a rolling pin over the bag. You can also do this in a food mill or food processor.
Put the crushed panko and the remaining ingredients marked with ○ in a bowl and mix to combine. Add 250 ml of beer and mix until blended.
The batter should be about the consistency of heavy cream. If it's too thick add a little more beer, mixing between additions.
Pour cooking oil in a frying pan and heat over medium to about 170℃.
Coat each piece of chicken in batter and deep fry.
To avoid the batter from cracking and falling off, turn the pieces over gently after about 30 seconds even if the surface has not hardened. When the pieces are golden brown, take them out and drain off the oil very well to finish.
Story Behind this Recipe
I love the taste of that famous chain's crispy chicken. So I tried re-creating it with ingredients I usually have in my kitchen! I got the idea for the crispy coating from the coating used for fish and chips. After many experiments I was able to recreate it. Speaking for myself, I'm about 99% satisfied!
Please be sure to use dried panko breadcrumbs! It's critical in re-creating that crispiness! I just add a tiny bit of soy sauce and honey as a hidden flavor. The amount of soy sauce is about the amount you'd use on one piece of sushi, and you just need one squeeze of honey.
