I'm looking for a red (could be pink but not yellow or orange or a cherry) variety for making tomato sauces with in addition to some of the other tomatoes I'm growing. When I've been making sauces, it seems like they are very thick or really runny and the water tends to separate out. I'm not sure if it's the tomatoes or the cook! I don't know if I'm adding too many roma / paste tomatoes or not. Here are the varieties I'm growing:
From a cook's perspective: San Marzano is the coveted Italian import for canning, tomato paste, or puree that is often specified in authentic recipes. The finest exports will often specify that they are San Marzano. The fruit is high in pectin, this gives sauce and paste a natural thickness. The finest quality of imported, glass bottled Italian tomatoes is traditionally San Marzano. Scatalone is a refined San Marzano. San Marzano 3 is an improved indeterminate vining type variety.
The variety that is a favorite for drying is Principe Borghese. They are small thick walled tomatoes. Principe Borghese is found dried and preserved in extra virgin olive oil through out Italy and used for export.
All of the above are good yield, particularly Principe Borghese.
Bavicchi and Scafati are good Italian seed companies if you want the real deal. Or, Victory Seed has good Principe Borghese and Heirloom Seeds is also reliable domestic seed provider.
I used a black---nyagous--for most all the sauce last year. Mainly because it was incrediblely prolific and rather bland fresh but developed a wonderful flavor when roasted. Don't know why my blacks were bland last year, most everyone else has a difference experience.
I don't find much use for the paste tomatoes as they don't seem to have much flavor.
After running tomatoes through a strainer to remove skins and seeds I put the sauce in a stainless pressure cooker. Bring it up to 15 psi and then shut it off. Then pour the sauce into a strainer and the water runs off leaving a very thick sauce. Then add the onions and carrot puree and spices.
