I normally keep mine in a dedicated Notebook, but for some unknown reason. I didn't add this particular recipe.I just got an app on my phone, it's called Recipe Keeper, it's for regular cooking recipes, but it can be adapted to tobacco recipes very easily. I've got all my homeblends on there and categorized, and I'm putting my commercial blends on there as well. On this app, if you have more than 20 recipes, you have to upgrade for $12.99, but you always have the ingredients stored, when you're thinking, what exactly did I put in this? It beats a spreadsheet easy.
But thanks Charley, I love the idea of an app....for those who want to know about the note book. I got it on Amazon.
