Make cold non-drinking preserve (6,3)
-r-e-e -d-

[elliemay1]

freeze dry?

[Baldric]

Freeze dry ?

[Captain2]

Freeze dry?

[carmel10]

Thanks to all three responses, but alas I don't think that freeze dry will do.
I'm fairly confident that the middle letter of the second (three-lettered word) is D: ?D?

I already had worked out that "freeze" fits the first word.
My best answer at present is FREEZE ADE ??
Any further help will be appreciated

[Captain2]

Where does the 'D' come from?

[scorpiojo]

What gives you the D, Carmel?

[elliemay1]

Which clue gave the 'd'?

[Captain2]

(I'm sure elliemay is stalking me tonight ;-)) )

[bibblebub]

but - make cold = FREEZE and non-drinking = DRY

so what's the intersecting clue?

[carmel10]

The intersecting clue is "Cross over the entrance."
four letters: -o--
I have taken this clue to yield ROOD, the fourth letter being the D which is the middle letter of the three-lettered word?

[scorpiojo]

Reverse rood to get door (entrance)

[elliemay1]

door?

[carmel10]

Thanks to you all! Reversing "rood" (= a cross set above entrance) to get "door" is clever! This has to be the best answer. Sleep well. Nite.

Thank you, Carmel. Nite :)
