The original recipe calls for you to make your own pesto sauce from scratch. I can't do this because it's too expensive and I don't have the necessary equipment needed to make the pesto (a food processor/blender). The pesto comes in little glass jars that are like 6 oz. each (at least that's how big I recall them being last time I used the jarred variety; this is a guesstimate).
Anyway, my question is, the recipe doesn't specify how much pesto you're supposed to use total in the recipe; I know you're supposed to use at bare minimum, a 1/2 cup. This is because the recipe states that the use of the pesto is divided (recipe doesn't state this in the ingredient list, but it does imply this in the instructions of the recipe). You combine a 1/2 cup of pesto with the ground beef. The other portion of it you spread onto the hamburger buns, and is essentially used as a condiment. I'm also making a double batch, so I'm guessing I should use 2 jars of the jarred pesto for a total of 1 cup?
One more thing I would like to ask about the recipe. It calls for breadcrumbs to be mixed into the meat mixture, which I know will act as a binding agent. However most recipes I see for burgers also specify to add egg to bind your meat, breadcrumbs (or I've seen crushed cracker used) so you have a cohesive mass. It does specify to add pesto sauce to the meat mixture, so should I worry about adding eggs
to this or not? If so, how many and should I worry about beating them prior to adding them to the meat mixture? Please specify (if I need to add eggs) how many I would need to add for a double batch.
