One small bug that interfered with my play the most -- when the animation is playing as you add ingredients, you no longer get the tooltip in the bottom right about what bottle you're hovering over. You have to move the cursor off the object and back again to highlight it. Since the ingredients mostly just varied in label color, it was a bit tricky to memorize all of the ingredients without the tooltip so I relied heavily on it. Maybe some art on each bottle could help player memorize them!
I did a little testing and noticed you can sometimes add an extra ingredient and still get credit for the recipe. I liked that it was a bit lenient, but I'm not sure it was intended?
I had a great time playing! Nice work
