Line a sheet pan with parchment or wax paper. Set aside.
Place strawberries in a large bowl. Cover completely with vodka (add more if needed). Refrigerate for at least 1 hour, or up to 5 hours if time allows.
Drain strawberries, reserve vodka for future use. Thoroughly pat strawberries dry with paper towel. (The chocolate will not stick if the strawberries are not dried well).
In a microwave-safe bowl, combine semisweet chocolate, milk chocolate and coconut oil. Microwave in 30-second intervals, stirring in between, until completely melted.
Pierce the stem-end of a strawberry with a fork and dip strawberry into the melted chocolate. Lift strawberry just above the bowl and twist around a couple of times to let excess chocolate drip off. Place strawberry on lined pan and repeat with remaining strawberries. Chill until the chocolate sets, about 15-30 minutes.
To drizzle strawberry with white chocolate for effect: Melt white chocolate using the same directions as above. Dip the tip of a fork into the chocolate and drizzle in a zig-zag pattern over the dipped strawberries. Let set in the refrigerator for a further 30 minutes, or until set.
Notes
Tip: For additional ideas to coat strawberries, dip strawberries into melted chocolate as above, then dip into crushed nuts, mini chocolate chips, chocolate flakes or coconut flakes.
