Clear fluid recipes before a colonoscopy (that aren’t just broth)
When your clinic has switched you to clear fluids (a “clear liquid diet”) — usually the day or evening before your colonoscopy — you still need something translucent to sip that does not taste like nothing. This page covers what counts as a clear fluid, why flavour can still exist in that phase, cookable samples from Sophie Hansen’s BowlPrep set, and when jelly stops near sedation. This advice works with your treating team’s written instructions. Not instead of them.
During the clear-fluid phase, a clear fluid is a translucent liquid with no solid bits (pulp-free). A practical check used in BowlPrep education is: could you, or your colonoscopist, see through it well enough to spot a tiny lesion on the bowel wall? If not, it is not clear enough for that phase. This is generic education — follow your clinic’s written list and hours. BowlPrep does not publish a national colour or cola chart. Flavour and nutrition can still exist on clear fluids. That does not make clear fluids a nutritionally complete diet, and this page does not claim nutrient amounts. A strained roasted vegetable broth — and jelly where your written list allows — can make the hours more tolerable. Within 6 hours of anaesthetic or sedation, no jelly, gelatin, or egg white — even if a clinic allows jelly earlier in the clear-fluid window. If in doubt check with your anaesthetist. This is generic advice and does not override any specific instructions from your doctor or clinic.

What is a clear fluid (the see-through test)
Clinic handouts might name approved drinks. They almost never give flavoured recipes. A clear fluid for this phase is a translucent liquid with no solid bits — pulp-free juice, not freshly juiced or blended. For a fuller definition, see What is a clear fluid?

A shorter way some readers remember the practical check: could you, or your colonoscopist, see through this and spot a tiny lesion on the bowel wall? Prefer the locked definition above when anything conflicts.
Flavour still counts on clear fluids
Flavour and nutrition can exist on clear fluids. That does not make clear fluids a nutritionally complete diet, and this page does not claim nutrient amounts. It is not reserved for low-fibre or white-diet days. Clinic lists name drinks; recipes make those drinks — and jelly where your written list allows — something you look forward to sipping through long, hungry hours.
Strained broths, pulp-free juices, and allowed jellies can still carry aroma and taste while staying translucent. The see-through test still applies: if you cannot see through it well enough, it is not clear enough for that phase.
Recipes that aren’t just plain broth
BowlPrep’s Colonoscopy Cookbook includes five clear-fluid recipes by Sophie Hansen. This free page shows cookbook photos — not full methods. Full methods for the clear-fluid set live in the paid cookbook (~A$8.99). One free full method (roasted vegetable broth) already has its own page.
Full method lives in The Colonoscopy Cookbook (~A$8.99) — not published on this free page.

If jelly is on your clinic’s written list, it may be allowed earlier in the clear-fluid window only as that list says. Separately, near anaesthetic or sedation the locked timing rule below applies (jelly, gelatin, and egg white stop within 6 hours).

More clear-fluid recipes in the cookbook
Two more clear-fluid recipes stay in the paid PDF and iOS app. Titles and methods are not invented on this page. When you want the full clear-fluid set to sip through those hours, it lives in The Colonoscopy Cookbook — PDF and iOS, about A$8.99.
Within 6 hours of anaesthetic or sedation
Keep two windows distinct. Your earlier clear-fluid window is set by your clinic’s written list — what drinks and jellies are allowed, and from when. The near-sedation window is separate: within 6 hours of anaesthetic or sedation, stricter rules apply even if jelly was allowed earlier.
Near-sedation rule (locked): Within 6 hours of anaesthetic or sedation, no jelly, gelatin, or egg white — even if a clinic allows jelly earlier in the clear-fluid window. If in doubt check with your anaesthetist
That line is not expanded here. If your written list and your anaesthetist differ, ask them. Do not treat this page as a personal fasting timetable.
What this page will not do
It will not invent fibre numbers, GI values, or bowel-prep volumes.
It will not tell you your clinic’s written list is wrong.
It will not cover day-count claims, GLP-1 timing, diabetes tables, after-colonoscopy meals, or “I accidentally ate something” panic FAQs — those stay on hold elsewhere.
Education from a GESA-certified colonoscopist and colorectal surgeon’s BowlPrep project — still generic food education beside your treating team’s written instructions.
Want more clear-fluid recipes to sip — beyond the free broth sample and the photos here? The Colonoscopy Cookbook holds the full Sophie Hansen clear-fluid set (methods included), plus the rest of the gourmet prep week. Separately, five free low-residue starter recipes (not clear fluids) are available if you are still on solids days.
