Why did my toffee turn out grainy instead of smooth?

Graininess comes from undissolved sugar crystals. Stir the butter, brown sugar, and salt over medium heat until the sugar is fully dissolved and the mixture looks uniform before you let it boil. Once it reaches a boil, keep the heat at medium and stir constantly for the full three minutes.

Can I use salted butter instead of unsalted?

Yes, salted butter works fine. Omit the 1/2 teaspoon of fine sea salt from the toffee base, since the butter already contributes enough salt. Keep the flaky sea salt finish on top, because that final salty pop is part of what makes the candy so addictive.

Why is my toffee soft and chewy instead of crisp?

Soft toffee was underboiled. The mixture must reach a full, vigorous rolling boil and stay there for exactly three minutes so enough water evaporates for the snap. Humid weather can also soften toffee, so on rainy days boil for an extra 30 seconds and chill the finished slab well.

Can I freeze Christmas crack for holiday gifting?

Absolutely, Christmas crack freezes beautifully for up to three months. Pack the broken pieces in an airtight container with parchment between layers, then wrap the whole container in foil. Thaw it sealed at room temperature so condensation never forms on the chocolate.

My chocolate seized into a grainy clump when I spread it. What went wrong?

Seizing happens when water touches melting chocolate or the chips get too hot. Sprinkle the chips over the hot toffee and let residual heat do the work, never return the pan to the oven. If it still seizes, warm 2 tablespoons of cream, stir it in, and spread the resulting ganache instead.

Instructions

Preheat the oven to 375°F. Line a 15×10 inch rimmed baking sheet with parchment paper, letting it overhang the edges.
Arrange the saltine crackers in a single snug layer covering the bottom of the pan, breaking a few to fill gaps.
Combine the butter, brown sugar, and fine sea salt in a medium heavy-bottomed saucepan over medium heat, stirring until the butter melts and the sugar dissolves.
Bring to a full rolling boil and boil for exactly 3 minutes, stirring constantly, until deep golden.
Remove from the heat and stir in the vanilla extract.
Pour the hot toffee evenly over the crackers and spread quickly to the edges with an offset spatula.
Bake for 5 to 6 minutes until the toffee is bubbling vigorously all over.
Sprinkle the chocolate chips over the hot toffee, let sit 2 to 3 minutes, then spread into a smooth layer.
While the chocolate is still wet, add the sprinkles, flaky sea salt, and pecans if using.
Refrigerate 1 to 2 hours until completely firm, then lift out and break into pieces.
