Combine lemon juice, 1/4 cup granulated sugar, whole egg, and egg yolk in a small saucepan. Whisk constantly over low to medium heat until the mixture thickens and reaches 176–185°F. Remove from heat and strain through a fine sieve into a bowl to remove any solids. Let stand 2 minutes, then add cubed butter and blend with an immersion blender until silky. Transfer to a piping bag, seal, and chill until fully cold.

Temper the white chocolate with yellow coloring until smooth and evenly colored. Divide the melted chocolate into spherical silicone molds, ensuring complete coverage. Tap the molds on the countertop to eliminate air bubbles. Invert molds over parchment paper to remove excess chocolate and save the remainder in a piping bag for sealing. Place molds upside down on a board and chill until firm.

Bring 1/3 cup granulated sugar, glucose syrup, and water to a boil in a small saucepan. Cook until mixture reaches 243°F on a sugar thermometer. Meanwhile, whip egg whites in a clean bowl on high speed to soft peaks, then gradually add remaining 1 tablespoon sugar and whisk to medium-stiff peaks. Carefully pour the hot syrup in a thin stream into the egg whites while whisking continuously. Continue whipping on high for 8–10 minutes until the mixture is glossy and stiff. Blend in vanilla paste. Transfer to a piping bag.
