I guess I don't have the taste buds to distinguish the difference between true San Marzano and everything else. I've tried a LOT of different canned tomatoes in marinaras, sauces, pizza, etc, and can't tell enough of a difference to justify paying 5x the price for something labeled San Marzano. If they were grown in around Modesto (90 mins from me), that would explain a lot.
Kind of reminds me of some blind whiskey/bourbon/wine tests I've seen. People's expectations change with knowledge of what they "think" they're drinking.
Side by side you'd and taste the difference.
Last year I met up with Anthony Falco of Roberta's pizza in Queens New York at the Napa Culinary Institute in the heart of CA's wine country in Napa CA. And we did a blind taste test of five brands of San Marzano style tomatoes. Some of the most expensive brands taste overly tinny or overly tart from too much citric acid. There were two brands one brand had two types that came out on top.
Third place was Valoroso Robusto also made by Stanislaus tomatoes in Stanislaus County CA..
Bolder taste seasoned a little heavier than the other two.
In second place it went to Bianco Dinapoli (sweet with very little tin taste) grown in central CA.
First place was Alta Cucina plum tomatoes, (very sweet zero tin taste zero citric acid taste)
Grown in Stanislaus County CA.
The most popular brand San Marzano tomatoes were Cento.
The Cento's are easiest to find around here came out close to the bottom of the list with only one being worse which was the Sanamerican brand.
There are plenty of good crushed tomatoes such as Stanislaus 711.
And Tomato Magic.
And Full-Red which is a puree.
Walk into almost any Italian restaurant or pizza joint worth a lick and I bet you will find one of the above used as their base.
Sorry for geeking out on tomatoes.
If you have a restaurant supply nearby you can buy #10 cans of Al Dente' for $5.00-$7.00 it really is the way to go to get a good base.
Stanislaus County California tomatoes really are the best in the world ask any Chef.
An awesome ready to go pizza sauce I love it on pasta and Arancini is Pizzaido Autentico pizza sauce.
Sorry, I get side tracked super easy when it comes to good food talk.
