Grill the almonds in the oven at 180°C (350°F) for 15 minutes.
Leave almonds to cool down a bit.
Put almonds in a food processor and mix until it reaches a purée texture. This procedure takes time and patience. Stop once in a while to scrape down the almonds with a spatule as they tend to pile up on the side of the bowl. You might need to do this up to 7 times, depending on each food processor.
DO NOT ADD ANY OTHER INGREDIENTS UNTIL YOU'VE REACHED THE PURÉE TEXTURE !
Add both sugars, honey, salt, and vanilla extract and mix again.
Put the spread into a covered jar and can be kept for at least a month in the refrigerator, but at my home, it never lasts that long.
