Pinkies thaw so fast...that's what I'd have done, & FYI, I always thaw right IN the water. Yes, it washes off some scent, but many snakes don't care, & if they do, that's when I "pinch-damage" the nose.
But from the size you said she is...even 2 pinkies is NOT enough food. You need fuzzies at least & probably small hoppers now or very soon. I agree, she truly just needed to take food once...because that little bit of food made all the difference in her tummy, & now her tummy says "More!" She will likely eat several pinkies at each feeding now, until you get larger prey.
I'm very happy she finally ate for you...I knew you could get this done.
Happy Dance!
