Macadamia

The macadamia is a tree indigenous to Australia, which produces a nut also known as the macadamia. Macadamia nuts are used in some of the sweets sold at Honeydukes. Macadamia nuts can trigger food allergies in humans, and thus Honeydukes posted a notice warning consumers against the presence of macadamias and other allergens in their products.
