Here are two recipes that have worked well for me over the years. One is honey-based and sweet and the other is sugar free.
Martha's Jacked Up Honey Roasted Almonds
3 lbs. (or 8 cups) uncooked, untreated natural almonds –
6 oz honey
½ cup BROWN sugar
½ cup melted butter
1 tsp salt
¾ - 1 tsp cayenne depending on your taste preference
2 tsp ground cinnamon
1/2 cup real Maple Syrup (don’t use artificial. Spend the money for the real stuff—it’s the only thing that works)
1-cup Jack Daniels bourbon (use any bourbon, but it should have some kick to it. Wild Turkey is a good alternative)
Garlic Smoked Sugar Free Almonds
3 cups or 1.25 lbs. natural, untreated almonds
1 egg white or ¼ cup Egg Beaters (an adhesive for the spices, no flavor is added)
2 tsp garlic powder
2 tsp celery salt
1 tblsp sea salt
½ tsp liquid smoke
I've been doing some experimenting, and found that cold smoking does produce a slightly better taste--more buttery. But, I'm not sure it's practical for most people. If interested, here a step by step tutorial I published adapting both recipes to cold smoking if desired.
