I actually did make some. Made up my own recipe.
Just took some dry Oatmeal, some Purina Strategy (which I crushed into "dust"),
and I think some bran, or maybe some grain, mixed with a LOT of molasses.
(wanted to make sure they taste yummy to the horse) Then, I used "Perform and
win" electrolyte powder. I wanted to make sure I knew the dose of electrolytes
was the same for each cookie, so I mixed in 5 doses of electrolytes into my
batter, then made one giant cookie on a cookie sheet, and baked (and baked, and
baked) until they looked right. I then cut that big cookie into 10 individual
cookie bars (each the same size), so each had 1/2 a dose per cookie of
electrolytes. I got out my seal-a-meal, and did the "shrink wrap" job on each
cookie, so I could carry in a saddle bag. It worked, and the horse ate them. I
can not give you any kind of exact recipe, cooking info or such. It was trial
and error. My main objective was to know exactly the dose per cookie, and this
method seemed to work, by cutting up the one giant cookie into "doses" after
measuring in a pre-determined number of doses of powdered electrolytes. I am not
big on electrolyting anyway, unless I truly see the need for that horse, and
that day. (I don't do it blindly as many do at given "stops" or time
periods) These were easy to carry, but I wondered if the cooking/baking
could break down the ingredients of the electrolytes, and change them in
anyway.
It was a whim on my part to try, and still have
some left, and don't plan on making any again anytime soon.
