Question:
What if you switch the order and you made the Borei Nefashos first, can you still make the Al Hamichya or not?
Answer:
Hello,
Although it is preferable to say Al Hamichya before Borei Nifashos, since it is a more prominent bracha, nevertheless if one mixed up the order, one still says Al Hamichya after saying Borei Nifashos.
Best wishes
