Use a candy thermometer to reach exactly 300-310°F (hard crack stage) for the perfect toffee texture—too cool and it won't set, too hot and it becomes bitter and burns the chocolate.

Parchment paper prevents sticking and makes it incredibly easy to break the candy into pieces; avoid foil as toffee can adhere to it during cooling.

Lightly toast pecans in a 350°F oven for 5-7 minutes before adding them to enhance their nutty complexity and prevent a soggy, undercooked taste in the final candy.

Pat saltines with paper towels to remove excess moisture, ensuring they stay crispy and don't become soggy when the hot toffee is poured over them.

Melt chocolate chips with a small amount of coconut oil, then let it cool slightly before spreading to achieve a professional-looking glossy finish that hardens with a satisfying crack.
