How long doChiffon pieslast in the fridge once opened?
Why the freezer is not an option here
The USDA marks the freezer as not recommended for this item, so the whole answer is a single field: 1 day to 2 days in the refrigerator after opening. It is not a warning: food held at 0 °F stays safe, so a not-recommended is a verdict on what would come out of the freezer.
Every storage figure the USDA publishes for this item
The refrigerator is the only place the USDA gives this item a storage time, as it does for 64 of the 466 foods the USDA lists. Within Baked Goods it is filed under Bakery.

Turning the range into a date
Two clocks run on this item: one from the day it went into storage and one from the day the seal broke. Both are listed below, 1 row in all.

Is this window about safety or about taste?
The answer at the top of this page reads 1 day to 2 days in the fridge once opened. What decides that is the food and not the shelf the source files it on: Chiffon pies, chocolate, lemon is an animal food, or made with one. Past it, throw it out rather than taste it: a perishable food can carry enough bacteria to make you ill while it still looks and smells fine.
Every figure assumes the food was sound when you stored it, that your refrigerator holds 40 °F or below and your freezer 0 °F or below, and that the package was handled normally.
It is past the date. Now what?
Say the calculator above puts Chiffon pies, chocolate, lemon past its 1 day to 2 days in the fridge once opened window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.
The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. The FoodKeeper entry this page is built from prints storage times and nothing else, so anything past them here is USDA and FSIS guidance rather than a figure from the source. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Is that a long time?
4 items in the Baked Goods list keep exactly as long as this item, 2 days, so they all share place 49 of 52 rather than being put in an order the data does not support. Nothing the USDA puts in the refrigerator keeps a shorter time, and 32 of those entries share this same figure.
Items that behave the same way
All 3 of the 6 items nearest this item keep exactly as long as it does, 2 days, so the ranking around it is a tie rather than an order.
Products the USDA rates in the same places
This is a common shape of record: 16 of the 466 products are rated in the same places, refrigerator after opening, and 8 of the nine slots are left blank on all of them. Sorted by how close their windows are to this one, the nearest are Pudding, Dinners and Liquid concentrate or ready-to-feed formula, and the rest of that group is what the list below draws on. Of the 8 shown, 5 keep longer than this one. The longest-keeping of them is Retort pouches or boxes at 4 days.

The rest of the Bakery shelf
The USDA puts this product on the Bakery shelf together with 15 others, and 12 of them keep longer outside the freezer. The shelf runs from Pastries at 14 months down to Macaroons at 2 days. Nearest this product by window are Doughnuts, Bagel and Macaroons, which is the order the list below is printed in. The order counts the longest window outside the freezer, so this item sits here at 2 days rather than at the 1 day in the fridge once opened its own answer prints.

If it has to keep longer than this
If it has to keep longer than 2 days, the Baked Goods aisle gives 46 products that hold at least twice as long outside the freezer. The smallest step up is Cream pies at 4 days against this one's 2 days; after it come Quiche, Cheesecake and Fruit pies. They are printed below in the order the step gets bigger, not alphabetically. The largest step the category offers is Spice/spices at 3 years. Twice as long is the cutoff used here, so a product a few days apart from this one is not treated as a step.

The record this page is built from
This page is built from a single FoodKeeper row, record 206 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 1 of the nine storage slots with a time, and the source prints its binding figure in days, so the window at the top of this page is the source's own number untouched. 1 slot is marked not recommended, which is an answer rather than a gap. It is filed under Bakery inside Baked Goods, which is where every shelf comparison on this page comes from.
Where these numbers come from
Every range on this page is published by the USDA FoodKeeper and reproduced unchanged. The multipliers, the rankings, the percentages and the dates are ours, computed from those ranges. Where the source gives a span such as 3 to 5 weeks, comparisons use the upper figure, and the full span is always printed.
Rankings cover only the items the USDA gives a usable figure for, and identical ranges share a place rather than being ordered arbitrarily. Neighbors are chosen by nearest storage time within the same category, never alphabetically: two foods filed next to each other by name usually have nothing to do with each other. The freezer is excluded from ranking because it flattens almost everything.
Where the USDA lists several kinds under one name, they share one page here and every kind keeps its own windows: the source prints them as separate rows, and a page that merged them would be inventing a figure the source never published. Comparisons and the place in the category are computed for the kind the plain name means — the shell egg for eggs, the can for tuna — which is settled name by name rather than by the order the source lists its rows in, and the page names it. Where the plain name means no single kind, the page prints no single figure at all and lists the kinds instead.
