How a single Canadian butter tart recipe evolved over twenty-six years
In short: Explore the subtle shifts in a classic Canadian dessert by comparing two versions of the Purity butter tart recipe, published twenty-six years apart.
This video examines the differences between the 1944 and 1970 Purity recipes. While the 1944 version suggests a high-heat start at 230ºC (450ºF) and includes ingredients like vinegar, the 1970 iteration features corn syrup and a lower initial oven temperature of 180ºC (350ºF).
The comparison also highlights practical changes in yield and technique, such as the 1970 method of plumping raisins in boiling water. The presenter notes that adjusting the baking temperature to 375ºF can produce better results.
