Marinate the chicken: In a large zip-top bag or bowl, combine the ginger juice and honey. Add the drumsticks, seal or cover, and shake or toss until the chicken is coated. Refrigerate for 4 hours to allow the flavors to soak in.
Prepare the breading station: Set out three shallow bowls — one with corn flour, one with the beaten egg yolks, and one with breadcrumbs.
Heat the oil: In a deep fryer or large, heavy-bottomed saucepan, heat the canola oil to 365°F (185°C). Use a thermometer to monitor the temperature for safe and even frying.
Bread the drumsticks: Remove chicken from the marinade and discard the marinade. Roll each drumstick in corn flour, then dip into the beaten egg, and finally coat thoroughly with breadcrumbs.
Fry in batches: Carefully lower two drumsticks into the hot oil at a time. Fry for about 5 minutes per batch, or until the coating is golden brown and the chicken is cooked through (internal temperature should reach 165°F/74°C). Let the oil return to 365°F between batches.
Drain and serve: Transfer cooked drumsticks to a plate lined with paper towels to drain excess oil. Let cool slightly before serving.
