For traditional ice-cream - Pistachio. I also love Faluda (some people spell it Falooda) - which in east Africa is made with Pistachio ice-cream, vermicelli noodles and rose water.
I worked with a guy who owned a Baskin-Robbin store in Tacoma. He got all of his ice cream from Alpenrose and made regular visits to Portland to get it.
The best soft serve I've ever had I got from the local Izzy's in Hillsboro. Can't stand most of their buffet but I can eat endless soft serve vanilla cones. For one thing it's really super cold.
I used to go to a Dairy Queen stand when I was a kid. It wasn't a sit in restaurant. Just a stand. And I would get those.
In Taiwan we go for shaved ice made from fruit puree' ....you pick out the flavor and make it yourself on a freezing cold grill after your meal which is cooked on the same grill...amazing tool can cook or freeze with the flip of a switch....it's called BING in mandarin which basically means cold. College areas are packed with these things...hot pot and grill and stir freeze your own desert after they come along and clean the hot grill...you can buy containers of the fruit ice at the market as well if you don't want to go out for it.
Just thought I'd mention having grown up on a dairy farm that Sherbet and Ice Milk are not ice cream!
When I was a little boy between the ages of about 5 and nearly 12 I was addicted to raspberry rippled ice cream so much that I craved it above ALL else. To this day I like to juice some raspberries and mix them with vanilla ice cream so that the raspberry juice is swirled into the ice cream in streaks. OMG that brings up wonderful memories of me, my dog, my ice cream, my bike, my fishing pole and my swim trunks and being ten years old in Oswego.
Daiquiri ice B-R’s used to have a seasonal Watermelon ice. That was my jam. Easy-going sweet tarts in the shape of seeds. So good.
When I was working at Boeing I kept two secrets from my wife: 1. I obtained my professional engineer's license from the state of Washington; 2. I learned some rudimentary reading and speaking Korean. I took her to a what was once a great restaurant, Inn at the Key in Jantzen Beach. After a great dinner and cocktails, we ordered Cherries Jubilee. Before they came to our table to prepare it, I sprung my two secrets. She was ecstatic as was I when I saw how happy it made her. I used my professional crimp to crimp my license number on a napkin just for fun. Then I spoke some new Korean to her which was different than the Korean shehad already taught me. This was topped off with aa gentleman in a tuxedo who prepared and lit the brandy on fire just before serving us. The perfect evening with window seats along the Columbia river.
I made a mistake with Umpqua....the best ice cream is Lochmead from Dairy Mart, not Umpqua...Lochmead rules!
