1. Wash the duck tongue, blanch it in boiling water, and take it out after 30 seconds. Mix the homemade marinade with water at a ratio of 1:1 and marinate for about 1 hour. You can mix it multiple times.
2. Preheat the oven to 200 degrees. Spread tin foil on a baking sheet and brush with olive oil. After preheating, spread the duck tongue flat on the baking sheet, brush evenly with olive oil and honey, and put it in the oven. 10 minutes and it's ready.
