A new test this morning revealed that "Classico" brand sauce jars are still thread-compatible with Oster blender bases.

A new base with a blade and gasket currently costs between $5 and $10 depending on which store or web site you're looking at.

Here are a couple of other blender tips:

-- Sometimes I run out of simple syrup and simply use a jar to make more on-the-spot.

-- All manufacturer-supplied blender gaskets shrink and lose their flexibility over time, so I've been buying 5-packs of SILICONE gaskets online. Now I use only silicone gaskets with my blenders. They are inexpensive and superior to the factory gaskets.

MORE INFO (and two photos) on using Mason jars with Oster blender bases:

-- There are at least three sizes of Mason jar mouths - Regular, Wide Mouth, and what I call small mouth. The "regular" mouth is the one which works with Oster blender bases. This jar is used for the 24-oz size of Classico sauces, not the 16-oz size jars.

Out shopping for jars? Bring your ruler and carefully look for these measurements:

Regular mouth (yes Oster!) jars:
Jar opening (outside diameter) is 2-5/8 inches.
Jar opening (inside diameter) opening is 2-3/8 inches.
Metal lid diameter is 2-3/4 inches and is shown in the 2nd photo below.

Small mall mouth (non-Oster!) jars:
Jar opening (outside diameter) is 2-3/8 inches.
Jar opening (inside diameter) is 2-1/8 inches.

Now go make a cocktail! :)
