Falooda

Uhlman's Farm is a little "corner" ice cream shop in Westborough, with vast amounts of parking, several different areas of picnic benches, and four windows with room for extensive lines. It's an actual farm - past the parking area is a field at least as big as the parking where I spotted half a dozen cows, and the low fences suggest they probably interact with visitors when given the opportunity.1

The large ice cream cups (the story is lengthy and apparently doesn't fit on the smaller sizes) have a detailed history of Uhlman's having started out as Smithfield Ice Cream in Worcester, which bought milk from Uhlman's, and did a fairly modern "merge with your supplier" back in 1969, and that the modern Uhlman's still uses locally sourced milk (though I suspect the handful of cows on-site isn't quite big enough for their entire supply.)

Everything

Uhlman's has one of the most thorough menus I've found so far - if I ever convert to a standard checklist form for these reviews, I'd probably start here, and then add a couple of novelties from elsewhere.2 While their menu is dominated by hard ice cream, they also have (hard) yogurt, basic soft serve3, and a range of No Sugar added, vegan, and "allergy-friendly" desserts.4
They have toppings (including Maple Walnut) and candy toppings (including nerds, gummy bears, and fruity pebbles) - they of course have chocolate jimmies but I couldn't find them on any of the signs.
They have four sizes of cups, cones, and sundaes (3oz up to 12oz) as well as a four-flavor "flight". They also have hand-packed pints and quarts, and five sizes of "machine-packed" ice cream to-go from pint up to 3 gallons. (Alternatively they have 9" round ice-cream cakes, priced about halfway between 1 gallon and 3 gallon buckets.)
This is also the third place I've seen with "Ice Cream Nachos" - waffle cone pieces with two baby scoops of ice cream and two toppings. Their "New England Weather-inspired" item is the "Cow-lossal Flurry". Other ice-cream-related drinks include frappes (and vegan oat milk frappes), freezes, floats, ice cream soda, frozen lemonade and frozen horchata slushies, crushed fruit smoothies, Falooda and Creamsicle.
They also have "girl scout cookie frappes" - Samoa and Thin Mint - amusingly, the thin mint one is topped with two thin mint cookies, but is based on mint oreo ice cream, which is probably some sort of branding crime...
They also have a "Pup Cup Sundae" - yogurt topped with chopped hotdogs(!), peanut butter whipped cream, and a dog bone.
The ice cream itself

While I was tempted by the Creamsicle and the Thin Mint Frappe, I originally planned to get one of my reference "crunchy + chocolate" combos - Butter Crunch and Extreme Chocolate (with chocolate jimmies). Unfortunately they were out of Extreme Chocolate so I substituted Cookie Monstah on the fly.

The crunch bits were quite good - not hard enough to hurt your teeth, just reasonably crunchy. The ice cream base was close to vanilla (good, but plain.) This is where I first noticed that the cookie monstah flavor was not quite what I was expecting...

It was blue! Specifically, the color of the Cookie Monster himself. I should have expected this, but most shops I've seen the "monster" flavor is green after the Fenway Park Green Monster. The cookie dough was good - sweet with some sugary crunch to it5.

Most likely choices are the Creamsicle and the Thin Mint Frappe, with an option of the Extreme Chocolate if they have it back in stock. Frozen Pudding and Fudge Ripple are also high on the list.
Ice Cream Trucks

Researching ice cream businesses in Massachusetts I've found a number of them that, while they have a street address on google maps, are only an ice cream truck that's available for events and catering. Uhlman's is both - they have two ice cream trucks available, they're even listed on the menu.

It's not quite as farm-first as Rota Spring Farm - the visible cow field is only about 2½ acres and is surrounded by houses, vs about 50 for Rota Spring and adjacent fields. ↩
-
At a glance, the one thing Ulhman's doesn't have is Raspberry Lime Rickies - which aren't really an ice cream thing but a friend of mine likes them so I've been noting the places that had them from the beginning. ↩
-
It also looks like they have chocolate dipped cones (plain and waffle), like Erikson's does, but not dipped soft-serve. ↩
-
The allergy-friendly option is comfortingly specific: "Dolewhip soft-serve made in a dedicated machine" (flavored in orange, pineapple, and twist.) ↩
-
Or maybe some of the butter crunch was still mixed in, but I'm pretty sure it was the cookie dough. ↩
