The Art of Layering Flavors
Quality bacon renders fat to flavor potatoes while staying crispy. Onions add sweetness, dill brings brightness. Heavy cream creates silky sauce binding everything while maintaining distinct textures. Puff pastry transforms - tender base with crispy edges.

When I pre-cooked potatoes too much initially, they broke apart in baking. Now I know minimal pre-cooking maintains perfect layers while still absorbing flavors.
This Savory Irish Potato Pie honors Irish culinary tradition - humble ingredients transformed into something extraordinary. Requested year-round, it delivers satisfaction in every slice, from St. Patrick's Day to simple family meals.
