- Let the mixture sit for about 10 minutes so the syrup separates.
Eden’s Recipe Tips
Toast the marshmallows more than you think — pale marshmallows won’t give enough flavor.
Don’t boil the syrup after adding marshmallows; low heat is key.
Letting the mixture sit before straining is what makes the syrup smooth.
If it thickens too much in the fridge, gently warm it or stir in a splash of hot water.
