Unsalted butter: 2 Tbsp (28 g), cut into small cubes

Salt: Pinch (optional, enhances flavor balance)
Vanilla extract: ½ tsp (optional, adds depth)
Optional toppings: toasted pecans, chopped mint, or a drizzle of honey for extra layers of flavor
Instructions
Prepare the blueberry mixture: In a medium‑sized saucepan, combine the blueberries, sugar, and water. Place over medium heat, stirring gently to dissolve the sugar. Let the mixture simmer until the berries burst, releasing their juices—about 5–7 minutes.
Reduce the sauce: Increase heat to medium‑high, bringing the mixture to a gentle boil. Reduce the volume by roughly half, stirring frequently to prevent scorching. The glaze should thicken slightly, becoming translucent and glossy.
Incorporate butter: Lower the heat to medium and add the butter cubes one at a time, stirring until each piece fully melts and is incorporated. The glaze will develop a silky sheen.
Season the glaze: Stir in the lemon zest, pinch of salt, and vanilla extract. Cook for an additional 2 minutes, allowing the flavors to meld.
Check consistency: Gently spoon a small amount onto a chilled plate. If it coats the back of a spoon and holds its shape, the glaze is ready. If it’s too runny, continue simmering for another minute; if too thick, add a splash of water.
Cool and store: Remove the saucepan from heat and let the glaze cool to room temperature. Transfer to a clean jar or airtight container. Refrigerate; the glaze can be stored for up to one week. Reheat gently on the stove or in a microwave before use.
