                Set your oven to 300°F (150°C) and line two baking trays with non-stick parchment paper
              
              
              
                02 - 
                Combine powdered sugar and almond flour, sifting together to remove any clumps and create a fine texture
              
              
              
                03 - 
                Beat egg whites (room temperature) into a thick meringue, adding the sugar gradually until peaks hold their shape, then gently mix in the vanilla and food coloring
              
              
              
                04 - 
                Carefully fold the meringue with the dry ingredients until the mixture achieves a smooth, flowing texture like lava
              
              
              
                05 - 
                Pipe small one-inch circles onto your baking sheets, then tap the trays firmly on the counter to get rid of tiny air pockets
              
              
              
                06 - 
                Leave the piped shells at room temperature for 30-60 minutes until a dry surface forms on top
              
              
              
                07 - 
                Pop the trays into the preheated oven and bake for 15-18 minutes until the shells feel firm and lift without sticking

                Once cooled, pair up shells of similar size and spread raspberry jam between them, sprinkling each with a bit of chopped pistachio
