Oil the inside of a 9×5-inch loaf pan lightly. Line it with parchment paper, leaving a little hanging over the edges, and oil the paper before placing it in the pan.

Chop the butter into 8 pieces and put it, along with the cream, into a microwaveable bowl. Heat it in the microwave until melted and warm, then set aside.

Pour water and corn syrup into a small saucepan. Slowly add the sugar, being cautious to avoid getting it on the pot's sides. Stir gently just enough so the liquid covers the sugar.

Warm the mix over medium heat until it's boiling. Cover it for a minute to let steam dissolve any sugar stuck on the pot's sides.

After uncovering the pot, attach a candy thermometer and heat the mixture to 320°F (160°C) until its edges turn light amber. Slowly add a small portion of the butter-and-cream blend, stirring with the thermometer’s base. Keep adding the rest gradually, stirring between additions.

The temperature might lower slightly after adding the butter and cream. Keep cooking until it hits 240°F (115°C), which usually takes about 5-10 minutes.

Carefully pour the caramel into your pan. Wait 20 minutes, then sprinkle with the sea salt. Let it set until it’s fully cooled, which can take around 3 ½ hours.

Take the caramel out of the pan. If it's too soft, chill it for about 30-45 minutes to firm up. Slice it into pieces—1-inch by 1/2-inch is a good size. Wrap each piece in wax paper or plastic wrap.
