Grab a 9×5-inch loaf pan and lightly coat it with oil. Place a parchment sheet inside, letting it hang over the sides by about an inch. Oil the paper as well and set it aside.

Slice the butter into small chunks and pop them into a bowl. Add the heavy cream, heat the mix in the microwave until bubbly and fully melted, then let it sit.

Pour water and corn syrup into a tiny saucepan. Carefully add sugar without letting it stick to the sides. Stir gently, just enough for it to blend into the liquid.

Crank the heat to medium and let the mixture bubble up. Put a lid on for one minute to release steam, which helps clean up sugar stuck on the pan sides.

Take off the lid and attach your candy thermometer. Heat until the sugar gets to 320°F (160°C) and a light amber hue forms. Slowly add about a sixth of your melted butter-cream mixture. Stir carefully each time before adding the rest in small portions.

When you add the cream and butter, the mixture cools off. Keep cooking until the thermometer reads 240°F (115°C), which usually takes another 5 to 10 minutes.

Gently tip the caramel into the pan you prepped earlier. After 20 minutes, sprinkle on the sea salt. Let it fully cool, which takes around 3 ½ hours.
08 -
Take the caramel out of the pan. If it's still sticky, chill it in the fridge for 30 to 45 minutes. Use a sharp knife to cut the caramels into your favorite shapes. Rectangle pieces about 1 inch by 1/2 inch are a good option. Wrap each one up in wax paper or plastic.
