Honey (Best Option)
1:1 (1 tablespoon honey per 1 tablespoon agave)Honey works well as a substitute because it contains fructose and glucose, similar to agave, which contribute to sweetness and help with browning reactions during cooking. Its viscosity helps the marinade cling to proteins effectively.
For best results, use raw or mild-flavored honey to avoid overpowering the marinade. Warm the honey slightly if it is too thick to blend evenly.
Compared to agave, honey may add subtle flavor nuances and a slightly thicker texture, but it maintains the marinade's balance and caramelization potential.
