Appearance
The appearance on the rosin was nice, opening up to a pale whitish beige color with a wet, terpy look. The rosin also had a smiley face imprinted in it which was a cool touch and I'm pretty sure Happy Hash Cat does this with a lot of his jar giving the “Happy” in the brand's name a nice nod. The jar was visually clean, with no contaminants visible to the naked eye or even under my phone’s macro lens. When I dipped my tool into it, the consistency was also nice with a nice wet, terpy and slightly stiff texture that holds its shape and is easy to work with.
The rosin came packaged in an authentic miron jar with the “m” stamped on the bottom. It had two stickers: a wraparound and a top. The top sticker had an image of blueberry muffins with the Rosin Foo logo in the upper left corner and the Happy Hash Cat logo stretching across the bottom. The wraparound sticker had a blue and white color scheme with a graphic of blueberry muffins on one section. The wraparound also included the name in the center "BLUEBERRY MUFFIN" in blue capital letters, with "Hand Washed Solventless Rosin" printed under it in black. There was also a small graphic to the left of the name that read "Wet & Terpy" in red. The wraparound also included both brand logos along with jar information such as the weight and micron range.
Aroma
The aroma is really nice and comes out rather loud as soon as you crack the jar. It has an actual blueberry muffin smell to it with that warm sweet airy pastry like aroma blended together with a sweet blueberry note. It genuinely smells like walking into a bakery while a fresh batch of blueberry muffins is baking in the oven. The blueberry isn't candy like at all, instead it comes across as a sweet natural blueberry. The smell is really nice and in my opinion lives up to the blueberry muffin name.
Taste
The taste mirrors the smell almost identically with a mouth coating sweet warm airy pastry baked blueberry muffin flavor. It's a really nice and flavorful terp profile that lives up to the name perfectly and lingers on the palate well, leaving behind those sweet warm blueberry pastry notes for quite a while, which I really enjoyed. It did have a slightly weird backend at times, coming out more at higher temperatures which took away from that good flavor a bit but apart from that I really enjoyed the taste. It's true to the name and delivers an flavor that is reminiscent of a blueberry muffin.
Burn/Smoothness
The rosin dabbed rather clean on the nail leaving behind a golden translucent color that had a slightly darker gold color but not that dark or murky color which would indicate there's quite a bit of contaminants. As for smoothness this is where things took a turn, it started off fairly smooth on the inhale but as you continue dabbing it gets noticeably harsher and had me coughing more than usual. This was more apparent at higher temperatures when I was testing how it burned on the nail. The burn was fine and remained clean, but the harshness was hard to ignore.
Effects
The high is really nice and pretty potent moves you with a nice head high and deep body high that'll have you very relaxed and just mellowed out. I thought muffins would be a great morning smoke with coffee, but this one hits a little too hard for that at times and would make me sleepy so I found myself enjoying these muffins more as a late night snack before bed, unless I had a chill day ahead of me.
Overall
This was a solid jar from Happy Hash Cat and Rosin Foos. The main reason I grabbed it was because I had tried Blueberry Muffin twice about a year ago. First was the Rosin Foos single source version, and later I got to try a friend's jar that was washed by Masterball Melts. I ended up enjoying the Masterball Melts wash quite a bit more than the single source one as it was more smooth and clean, so I figured I'd give the strain another shot with this version washed by Happy Hash Cat but sadly it was more reminiscent of the single source one and wasn't as clean and smooth.
Happy Hash Cat is a California based hash maker who has collaborated with a number of respected brands over the years by washing their material, including Mendoja Farms, Symbiotic Genetics, Sobe Farms, Oke Tree Orchids, First Class Concentrates, Terps HQ, The Firm, and many more like this one cultivated by Rosin Foos brand whose cultivar is The Plant Scientist. Happy Hash Cat has also competed in some hash competition and has won two well known ones that had some good competition, First Place Rosin at the Pure Melt Meltdown in 2024 with Grape Gas cultivated by 365 Farms, First Place Rosin at Ego Clash Barcelona in 2025 with cultivated by Mendoja Farms.
This jar checked pretty much all the boxes for me. The appearance, aroma, flavor, burn, and effects were all on point, making for a really enjoyable experience overall. The only area where it fell short was smoothness, which is an important category for me since I value clean hash and enjoy being able to take a full inhale without any background noise or irritation. As I mentioned, it started off fairly smooth, but as I continued dabbing it went on and became noticeably harsher and had me coughing way more than usual. Aside from that drawback, this jar checked all the boxes and was enjoyable.
This was a solid jar from Happy Hash Cat and Rosin Foos. I really enjoyed the blueberry muffin terp profile, as it was true to name with a nice aroma and flavorful taste that translated well from nose to palate. I probably wouldn't grab this one again due to the smoothness not quite meeting my personal standards and the slight weird taste towards the end. I would have definitely grabbed this one again though if the smoothness had been up there though, as the appearance, aroma, effects and burn all checked the boxes. Shoutout to Happy Hash Cat and Rosin Foos!
