thats such a great point!! my best replication to date was with loos home run inn recipe. as per the ingredients, puree, salt, pepper...thats it...the sausage and cheese added to it, it was great.....with aurelios a guy i worked with at aurelios in oak brook terrace Ill. i was a bus boy dish washer, he was a cook. said it was puree, water and a bag of spices they would add which was mostly sugar....he now owns his own joint in west burbs, but he swears people like their sugar fix, and aurelios was king of sugar....hmmmm. im now thinking, salt, pepper, sugar, pureem maybe a little water.....hmmm. good discussion!
