Special equipment: a chinois or strainer
Add the Rye Infused Peanut Butter, butter, salt and sugar to a pot and heat through on medium heat until combined, about 5 to 8 minutes.
Combine the peanut butter with the rye and freeze overnight. Strain through a coffee filter-lined chinois 2 to 3 times to remove the oil. Reserve the infused peanut butter and rye separately.
