Is it just a matter of size? The manual says that the FourSide jar is "great for smaller-yielding recipes" and that the WildSide is "great for larger-yielding recipes". But is it the case that smaller recipes ONLY work in the FourSide, or could the WildSide be used too? I was under the impression that the WildSide would work for small and large recipes, but the manual says "please prepare the recipe with the jar listed". Really?
Or is it also a matter of what is being blended? The manual says that the FourSide jar is great for sauces, dressings and nut butter, and that the WildSide is great for breads, quick breads and frozen desserts. However, many of the frozen desserts in their cookbook then call for the FourSide jar. Confusing.
What if I'm using the Blendtec with recipes other than the ones in the cookbook, how should I choose between one jar and the other?
I just bought a Blendtec at Costco that came only with the WildSide jar. I'm considering returning it and buy the package that comes with both jars, if the FourSide jar really is required for some uses.
