I could find out what jiggery–pokery means (dishonest or suspicious activity), but what does "pure applesauce" mean? And when, where, by whom, and how was this expression created?
Otherwise, the Court says, there would be no qualified individuals on
federal Exchanges, contradicting (for example) the provision requiring
every Exchange to take the "'interests of qualified individuals'" into
account when selecting health plans. Ante, at 11 (quoting
§18031(e)(1)(b)). Pure applesauce.
It does seem that Scalia didn't just make the phrase up, since it existed since at least the 60's *.
* I'm assuming those references aren't all about apple sauce that's pure.

From Eric Partridge, A Dictionary of Slang and Unconventional English, fifth edition (1961):
The relevant definition of sauce in Partridge is as follows:
J.E. Lighter, The Random House Historical Dictionary of American Slang (1994) offers this more elaborate, two-definition entry:
So applesauce, as used at the end of the OP's quotation simply means "baloney!"
A Google Books search doesn't find the Dorgan/Zwilling example mentioned in Lighter, but it does find two instances (both by the same author) from Collier's Magazine in 1921. From H.C. Witwer, "Auto Intoxication," in Collier's (January 1, 1921):
And from H.C. Witwer, "The Shooting Stars," in Collier's (June 11, 1921):
These are the earliest two matches in Google Books search results, although the expression is quite common by the mid-1920s, it's euphemistic qualities making it a favorite choice in periodicals such as Boys' Life.
