To avoid over-whipping, stop as soon as the foam is thick and fluffy (not butter-like). If it accidentally over-whips, gently stir in 1-2 tablespoons of cold milk to loosen it. For a healthier twist, reduce sugar in vanilla syrup or use unsweetened varieties. Use organic ingredients for a cleaner taste, or consider pure vanilla extract/bean paste with natural sweeteners like maple syrup or honey. For dairy-free, use oat milk (barista blend) or almond milk (full-fat) with coconut cream. For keto/low-carb, use sugar-free vanilla syrup and unsweetened almond or coconut milk.
