They are a hard nut to crack. Could always be found in the toe of a Christmas stocking. Not a favorite - pecans and almonds rate above him. Brazil nuts the last on that scale.
Hazel nuts seldom eaten; preferred in the butters such as Nutella or the newer Jiffy. My aunt would use walnuts when making divinity; along with her pecan divinity. Loved divinity but could eat very little - jaws would lock due to the sweetness.
When a recipe calls for walnuts, pecans are normally used. After all, cook’s choice. Right?
I love Brazil nuts; they’re one of the lower-carb ones, and a great snack on a low-carb diet.
If I recall, those were hard to crack, too. I’ve never bought them in-the-shell, but sometimes our stockings had a mixture of nuts, not just walnuts. My Grandmother always made our stockings up at Christmas, and I think nuts were something she didn’t get much of as a child herself, so they were a special ‘holiday’ thing. :-)
