1. In a bowl, add garlic, ginger, grated pork and ingredient A. Mix well to combine. Set aside.
2. Drain the topinambour and gently pat them dry with a paper towel. On a slice of topinambour, place about 1 tbsp filling from #1 and spread. Cover with another slice of topinambour on top and press down to make a sandwich.
3. Combine 2 eggs with milk. Coat the lotus roots 'sandwich' with katakuriko/potato starch thinly. Dip it in egg mixture, and finally coat it thoroughly with Panko (bread crumbs).
4. Put a tiny amount of panko in the hot oil to check if it is ready. If it sizzles, it's ready! (or stick a chopstick in the oil and see if bubbles start to appear around the chopstick). Remove excess panko from your 'sandwiches' and press them gently. Fry them both sides until browned.
