Prepare Gelatin: Place the 12g of gelatin sheets in a bowl of cold water. Make sure they are fully submerged. Let them sit for about 5-10 minutes until completely softened.

Infuse the Milk: While the gelatin soaks, pour the 300g of milk into a small saucepan. Add the 2 Earl Grey tea bags. Turn the heat to low and gently warm the milk. You want to see steam rising and small bubbles forming around the edges, but do not let it boil. Let it gently simmer for about 10 minutes, or until the milk is a deep, creamy tea colour. Gently press the tea bags against the side of the pan with a spoon to extract all the flavour, then remove and discard them.

Dissolve Sugar and Gelatin: Remove the saucepan from the heat. Add the 35g of granulated sugar to the warm tea-infused milk. Take the softened gelatin sheets out of the cold water and firmly squeeze them to remove any excess liquid. Add the squeezed gelatin to the warm milk mixture. Whisk continuously until both the sugar and gelatin are completely dissolved. There should be no grains or granules left.

Add the Cream and Strain: Pour in the 150g of heavy cream and whisk until it is fully incorporated and the mixture is smooth. Place a fine-mesh sieve over a large liquid measuring cup or a bowl with a pouring spout. Pour the entire panna cotta mixture through the sieve. This essential step will catch any stray tea leaves or undissolved bits of gelatin, guaranteeing a flawlessly smooth final texture.

Fill Molds and Chill: Gently pour the strained mixture into your chosen serving glasses, ramekins, or panna cotta molds. If you see any small air bubbles on the surface, you can gently tap the molds on the counter to bring them to the top and then pop them with a toothpick. Cover each mold with plastic wrap and place them in the refrigerator to chill for at least 8 hours, but preferably overnight. This long, slow chill is what allows the panna cotta to set to that perfect, delicate wobble.

Add Topping and Serve: Once the panna cotta is fully set, it's ready to serve. If you like, top each one with a spoonful of milk foam or a dollop of lightly sweetened whipped cream. Enjoy it straight from the fridge for the best cool, creamy, and refreshing experience.
