We sell dough pretty often. The people that buy dough are not going to buy a pizza from you that night because that is not the experience they are seeking at that moment. These are all carryout orders (as opposed to delivery). I do not see appreciable food safety risk in the dough sale.
So what happens… Customer calls and comes in. We get the chance to interact with them hopefully creating a positive impression. They buy something we make a couple of dollars profit on. We do NOT loose a regular sale and we stand to gain a chance for regular business when the experience they are seeking is a fully cooked pie.
On the other hand, I agree with the food safety and regulatory comments on sauce. Even though it is highly acidic and therefor not a huge food safety risk, the risk is still there… especially if they use it as a dipping sauce and do not heat it as it would be on a pie. You cannot just ladle some into a jar and sell it. We do not sell sauce. I do not agree with the lost sales position though. Again, that customer is not looking to buy a fully prepared pizza and will simply buy another bottled sauce at the grocery store while the interaction with them could possibly have created a customer relationship that was beneficial. In other words I see the other side of that coin; refusing to do it may give up an opportunity to sell pizza in the future.
If I were willing to go through the regulatory hurdles and thought I could sell a bunch of it I would go for it. Before I did it myself though, I would approach some small food producer and see if I could not get it made up in some reasonable quantity.
Pizza recipes are not rocket science. We have had a couple of hundred employees over the last 18+ years that could know how we make our sauce. I do not place a lot of value on a “secret recipe”. In fact, in my business brokerage and business valuation activity I would place no value on it whatsoever.
