Frozen sap in buckets tonight

[Hunt4sap]

All buckets tonight here in NE Ohio were about 1/2 way frozen.
I collected only about 6 gallon s but my question is, I'm evaporating my other 16 gallons tomorrow morning and the 6 gallons ( that I collected 1/2 frozen today)are in separate buckets from the 16 gallons I collected a couple days ago( been kept in sealed food grade buckets with gasketed lids in fridge)
As long as the 1/2 frozen sap thaws overnight ( probably same temp as ones in frgidge) what if anything does this affect when evaporated?(6 gallons in somewhat heated side of barn, to keep waterlines from freezing)it stays about 40 degrees constant with help from 2 electric baseboard heaters.
I have a real hard time believing that as long as these are preheated ( which I always do over turkey fryer and 12*20" ss pans and propane) that they will have a poor affect on rest of sap( don't understand how if sap freezes it is any less sugar content( which I've read from other places on here at different times before)
Thanks for all your thoughts and or advice.
Read multiple times that people throw out frozen sap b/c it's somehow transformed from sap to mostly water???

Sugar doesn't freeze, only pure water freezes. Some sugar gets trapped in the ice, but not a lot.

Ok, that makes sense
All buckets we're only half frozen, only water content froze rest was the sugar that wasn't frozen
O well, I'll boil it all off tomorrow morning, luckily wasn't like full 3.5 gallon buckets, which I had in 2016 a couple times( was a nice surprise for my first year tapping...)

To feel better and save some time, why not google about our American Natives and maple syrup? I believe the American Indian taught us about maple syrup. In any case, they made fine maple syrup BY LETTING IT FREEZE. Remove the ice, let it freeze again. Remove the ice. Repeat until it is the consistency you want.

Between cooking, I put my unfinished sap in my man cave beer fridge (set to 26.5 degrees F). When time to recook, I remove the ice first.

So my question to you: Why not simply remove the ICE and go on? It saves you much cooking time at little waste cost!

That's correct. Throw the ice out...it's mostly water, the sap that's left has been concentrated by a smidge.

Ok
Thanks for replying all
In my mind I thought even if there's a small amount of sugar in ice with how little syrup I made in 2016 if I can take a little longer boiling the slushy ice along with liquid I could gain that small amount of sugar trapped in ice/slush back to make more finished syrup ( but it sounds like it's not worth my time and efforts to add this slushy mixture into my turkey fryer preheater)
