Prep the tray: Line a baking sheet or any flat tray with parchment or wax paper.
Clear space in your freezer so the tray can sit flat.
Mash the raspberries: In a bowl, lightly mash the raspberries with a fork. You want small pieces and some juice, not a smooth puree. If you prefer seed-free, press some berries through a fine sieve.
Mix the base: In another bowl, stir the yogurt with honey or maple syrup to taste, plus vanilla and a pinch of salt.
Add lemon zest if you like a brighter flavor.
Combine: Fold the mashed raspberries into the yogurt. Don’t overmix—streaks of pink look pretty and keep some raspberry bursts intact.
Bag it up: Spoon the mixture into a piping bag fitted with a small round tip, or into a zip-top bag and snip a small corner. If you don’t want to pipe, use a teaspoon.
Pipe the drops: Squeeze small dots onto the lined tray, about 1/2 inch wide.
Leave a little space between them so they freeze separately.
Freeze: Place the tray in the freezer for 1 to 2 hours, or until the drops are firm to the touch.
Transfer and store: Once frozen, lift the drops off the paper and move them to an airtight container or freezer bag. Label with the date.
Serve: Enjoy straight from the freezer, or let them sit at room temperature for 2 to 3 minutes for a softer bite.
