"The Shamrock Shake is a seasonal dessert sold at McDonald's during March, to celebrate St. Patrick’s Day. Although the recipe has never been publicly released, it is widely believed that the flavoring used in the shake has significantly changed since its creation. Recent debate has questioned whether the Shamrock Shake is simply a vanilla shake dyed green, or if additional flavors have also been added. The ingredient list disclosed by McDonald’s does not specifically identify mint flavoring as one of the additives to the Shamrock Shake syrup[1], but in March of 2009, a public accounting firm based in Chicago, Illinois designed and conducted a double blind taste test comparing the taste of the vanilla shake, to that of the Shamrock. While the texture and consistency of the two shakes were nearly indistinguishable, over 98% of the respondents indicated that a subtle mint flavor is the differentiating factor between the two products. McDonald’s has not publicly commented on the results of the taste test. Sh" - Thomas Hawk from Bookmarklet

i used to get these when i was little... just about every year on my birthday. - Trish Haley

apparently not all McDonald's have them today. Thinking about stopping by one today and checking it out. - Thomas Hawk

I think that they should sell the Shamrock Shake all year long though. It's tasty. - Thomas Hawk

Ha reminds me of that Simpsons episode; Chief Wiggum: “I miss Shamrock Shakes, but they ain’t coming back ’til March.” Lou: “You know, Chief, Shamrock Shakes are just vanilla shakes colored green.” Chief Wiggum: “Well, I taste the flavor. It’s a very mild mint.” Lou: “Well, maybe ’cause it’s a minty color, your mind is fooling your tongue.” Chief Wiggum: “I know what I taste.” Eddie: “I gotta go with Chief on this one.” Lou (sarcastically): “Whoa, there’s a big surprise.” - Andrew Smith

I wasn't aware the Shamrock shake made a Simpson's appearance. That's great. - Thomas Hawk

I love Shamrock Shakes, but they haven't sold them in Canada for years! - Chris Rivait

damn. now I really want one. going to have to check out now and go see if the one here in downtown SF has the shakes. - Thomas Hawk

I've tried to get one at 3 different McDonald's, but no luck. They either don't sell them or have been out. I hadn't been in McDonald's for yeas, so I really have no reason to go back. A local place sells mint shakes and I'd rather spend my money there. Sorry Ronald. - Gary H

I'm sitting in the downtown sf mcdonalds right this very second drinking one. It's magically delicious. - Thomas Hawk

awww man! now i have to go looking for a shamrock shake because thomas has one. and matt and eight other people. - Trish Haley

I can definitely taste the mint. I'd be in trouble if they sold these all year long. I think the secret ingredient could be crack. - Thomas Hawk

hee hee - Trish Haley

Damn that was good. Now off to go shoot some abandoned warehouses in Alameda with some high school kids. - Thomas Hawk

One thing we know for sure - there's no ice cream in it. - Anthony Citrano

I tried to get one yesterday - ON ST. PATRICK'S DAY! - and they were out. Hmmph.:-( - Lisa L. Seifert | FHG™

Don't feel bad, Lisa. We have four McD's in my town and NONE of them had Shamrock Shakes. And from what I understand, none of them were even carrying them at all this year. It's a crime, I tell ya. - Hookuh Tinypants

Why do the McDonald's without Shamrock Shakes hate on the Irish so much? Luck for me the one in downtown SF was ready to go! - Thomas Hawk

I should've asked that at the last one I stopped into yesterday. "Yo, why you hatin' on the Irish, bro?" - Hookuh Tinypants

"My shamrock shake brings all the boys to the yard...damn right it's better than Hawk's, I could teach you but I'd have to charge.." - The Real sofarsoShawn

I got one at McDonald's in Milford, PA: http://www.flickr.com/photos... - Morton Fox

McD's needs to be paying for this advertising. I bought a Shamrock Shake for the first time in I don' t know how many years because of FriendFeed! :D - ChiliMac
