Preheat the oven to 300 °F. Spread the almonds, walnuts and pecans in a single layer on a baking sheet and roast for 12-15 minutes until fragrant. Remove from the oven and let cool slightly.
If needed, pop the popcorn as per your favorite popping method.
Butter or grease a large bowl and add the popcorn and nuts. Grease a large cookie sheet and set aside (I use the same one as I toasted the nuts on once it is cool enough to handle in order to minimize dishes!).
Heat the butter in a medium saucepan over medium-low heat. Once melted, add the sugar, syrup and cream of tartar and cook for 5 minutes, stirring constantly until the sugar is completely dissolved and the mixture is just starting to bubble.
Remove the mixture from the heat and stir in the salt and vanilla.
Pour the mixture over the popcorn, mix well and spread out onto the prepared cookie sheet to cool.
Allow to cool for 1-2 hours, then break into pieces and package.
