Prepare the muffins as directed, using orange juice in place of ½ cup (120 ml) of the milk and adding the orange zest and poppy seeds to the dry ingredients before dividing the batter among the muffin cups.
To make the glaze:
While the muffins bake, whisk together the orange juice and honey in a small bowl.
Allow the muffins to cool for 5 minutes, then dunk the top of the muffin into the glaze.
