Macadamia Nut Brittle is a crunchy, nutty, sweet candy that makes for an easy year-round treat. Crumble it over homemade vanilla ice cream, place it in your candy bowl at work, serve it at your holiday party, or package it up with a plastic bag and a ribbon for a thoughtful gift.
Lightly butter a 9 x 13-inch pan or set aside a silicone baking mat.
If macadamia nuts are whole, chop coarsely and set aside.
In a large saucepan stir together sugar, water, and corn syrup. Place a lid on the pan. Once mixture has boiled for 1-minute, remove lid and keep boiling without stirring the mixture. (Stirring will make mixture crystalize.)
Cook until syrup is golden and a thermometer reads 300°F. Remove from heat.
Add macadamia nuts, vanilla, butter, and baking soda. The mixture will rise in pan. Once safe to do so, stir together using a wooden or heat resistant spatula. Do not unnecessarily stir mixture as it increases the chances of crystalizing.
Pour and scrape immediately into buttered pan.
Using a spatula press and stretch brittle to size of pan.
