So when I want to say "You can choose an apple and/or pear, and a bottle of soda and/or juice." Is there a better way to say this, without the clump of and/or?
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
You can have any of an apple, a pear, soda and juice.
It's not elegant, but it is clear.
Longer, but probably more common would be, You can have an apple, a pear, soda, juice or any combination.
As noted in FumbleFingers comment, it is not clear as to whether the person can have any combination whatsoever (which is what the above answer suggests) or whether this is more like the forms used in Chinese menus in the US in the 1950s to 1980s which directed you to choose one from column A and one from column B.
Your choice might be thus expressed as
This assumes that you will choose at least one fruit and one drink.
