Toffee

Good toffee is all about temperature control. This recipe walks through three critical stages: stir constantly to 212°F (100°C), stop stirring until 236°F (113°C), then stir again with walnuts until you hit 290°F (143°C). Each stage matters, and a candy thermometer is essential here.

The baking soda stirred in at the end creates tiny air bubbles throughout the hot candy, giving the finished toffee a lighter, more brittle snap instead of a dense, jaw-breaking chew. Work fast once you add it because the mixture foams up and starts to set quickly.

Pour it onto a buttered cookie sheet and score into squares immediately. The toffee will flow back together, but those score lines become clean break points once it hardens.

Chocolate wafers placed on top of the still-hot toffee melt on contact. Spread them into a smooth layer with an offset spatula, then scatter chopped pecans over the chocolate before it sets.

Pro Tips

• Use a reliable candy thermometer clipped to the side of the pan. Even 5 degrees off can mean the difference between chewy and crunchy.
• The “stop stirring” phase between 212°F and 236°F (100°C and 113°C) prevents crystallization. Stirring during this window can cause the sugar to seize into a grainy mess.
• Butter your cookie sheet well. Under-greased pans mean you’ll be chiseling toffee off the surface.
• Store toffee in an airtight container between layers of wax paper. Humidity is the enemy of crisp candy.

Variations

• Almond toffee: Swap the walnuts for slivered almonds for a classic English toffee style.
• Sea salt finish: Sprinkle flaky sea salt over the melted chocolate before it sets for a sweet-salty contrast.
