ok, I have a Simac Gelataio Magnum Plus. It is a self contained refrigerated unit with a
removable 1 quart bowl. This is the second Simac I have had-the first lasted at least 20 years.
For ice creams I usually use a stirred custard base of 1 cup each heavy & light cream, 2-3 egg yolks and 1/2 sugar. For some ice creams-vanilla, coffee, nut etc, I will steep the flavoring in the scalded cream for a day before I make the remaining base. I find this intensifies the flavor. Always remember that cold food has to be more highly flavored. I have just started playing around with other types of bases but haven't been good about marking which work best.
I will buy the cardboard quart containers to put the ice creams in when it is done churning. The only problem with them is that they are cumbersome for storage.
I have had as many as 60 people for the ice cream social but that was unusual. Usually it is between 20 and 40 people. I make a double batch of big flavors-vanilla, armagnac hazelnut praline but just a quart of the rest. But I usually make over ten flavors of ice cream so that makes 3-4 gallons of ice cream. Over the week before the party I will make and churn the bases. It is a process since these are cooked custard bases but on some of them I can double the custard and make two or three bases with it.
I usually clear out my refrigerator freezer the day of the party and put all the ice creams in there. If there are a lot of people there at once we might put the containers in an ice bin on the counter. Unless it is very hot that will keep them.
