The green-hued, mint-flavored milkshakes will be offered at select McDonald’s locations beginning Feb. 21, according to an announcement from the chain. McDonald’s (MCD) offers the sweet treats every year leading up to Saint Patrick’s Day, typically beginning some time in February.
As in years past, fans are reacting to the return of the seasonal treat with enthusiasm — a lot of enthusiasm.
Though the Shamrock Shake has a cult following in its current iteration, the first recipe, which hit stores in 1970, used lemon-lime sherbet, according to Vox. It wasn’t until 1983 that McDonald’s starting selling the mint-and-vanilla confection fans know and love today, Vox adds, although some fans still say there’s a hint of lime in the frothy concoction.
