📖 Instructions

1. Prepare your pan: Lightly butter an 8x8-inch (20x20 cm) square baking pan. Line it with parchment paper, making sure to leave an overhang on two opposite sides. This creates 'handles' that will make it super easy to lift the cooled caramel out of the pan. Butter the parchment paper as well. This double buttering prevents sticking and makes removal so much easier later on. Trust me, it's worth the extra step! Set this prepared pan aside for now.
2. Measure and combine: In a large (I mean, really large—it's going to bubble up quite a bit!) heavy-bottomed saucepan, combine the granulated sugar, light corn syrup, and water. Give it a gentle stir just to moisten all the sugar. You want a heavy-bottomed pot to distribute heat evenly and prevent scorching.
3. Start cooking (Stage 1 - Sugar Syrup): Place the saucepan over medium heat. Cook, stirring occasionally, until all the sugar has completely dissolved. The mixture should look clear and smooth, with no gritty sugar crystals remaining when you rub a little between your fingers. This usually takes about 5-7 minutes. Once it reaches this point, stop stirring.
4. Add butter and cream: Carefully add the butter pieces and heavy cream to the sugar syrup. Don't worry if it cools the mixture down temporarily; that's totally normal. Stir gently until the butter is fully melted and incorporated into the cream mixture.
5. Continue cooking (Stage 2 - Caramelization): Insert your candy thermometer into the mixture, making sure the tip doesn't touch the bottom of the pan. Increase the heat to medium-high. Bring the mixture to a boil, then reduce the heat slightly to maintain a steady, rolling boil. Now, here's the crucial part: cook without stirring too much. Occasional gentle stirs are fine if you see it sticking, but constant stirring can cause sugar crystals to form. Your goal is to reach 245-248°F (118-120°C). This is the 'firm ball' stage. Be patient, it might take 20-30 minutes, or even a bit longer. The mixture will start to darken and turn a beautiful golden-amber color. Don't walk away from the stove during this stage—it can go from perfect to burnt in a flash!
6. Reach the right temperature: Keep a close eye on that thermometer. As it approaches the 245°F (118°C) mark, the boiling will become thicker, and the color will deepen. Once it hits 245-248°F (118-120°C), immediately remove the saucepan from the heat. Don't let it overcook!
7. Add vanilla: Carefully remove the candy thermometer from the hot caramel. Stir in the vanilla extract. Be cautious, as the steam will be very hot. Stir until the vanilla is fully incorporated. The aroma here is just heavenly, a true reward for your patience!
8. Pour into the pan: Immediately and carefully pour the hot caramel mixture into your prepared 8x8-inch pan. Do NOT scrape the sides or bottom of the saucepan; any crystallized sugar bits could ruin the texture of your caramels. Just let it flow into the pan naturally.
9. Cool completely: Let the caramel cool undisturbed at room temperature for at least 3-4 hours, or ideally overnight, until it is completely firm and cool to the touch. Resist the urge to poke or prod it! Proper cooling is essential for the perfect chewy texture.
10. Cut and wrap: Once completely cooled, use the parchment paper overhang to lift the entire block of caramel out of the pan and onto a cutting board. Using a large, sharp, oiled knife or a pizza cutter, cut the caramel into 1-inch (2.5 cm) squares. If your knife sticks, lightly oil it between cuts. For individual wrapping, you can use small pieces of wax paper or cellophane wrappers. Simply twist the ends to seal.
11. Store and enjoy: Store your delicious homemade vanilla caramels in an airtight container at room temperature for up to 2-3 weeks. In warmer climates, you might prefer to store them in the refrigerator to prevent them from becoming too soft, just let 'em come to room temp before eating for the best chew. Share them (if you can bear to!), gift them, or simply savor these little bites of sweet nostalgia yourself!
