Questions about cheese and mushroom flan
Four questions chosen by the facts above, so every food answers differently.

A typical portion (300 g, one serving) gives 846 kcal. Per 100 g the figure is 282 kcal.
Is cheese and mushroom flan high in vitamin B12?
Yes. Flan, cheese and mushroom, homemade has 0.0013 mg vitamin B12 per 100 g, 52 % of the NRV, above the 30 % threshold for a “high in” claim.
Are these figures exact for cheese and mushroom flan?
No. They are calculated from a standard recipe in the UK Composition of Foods Integrated Dataset (CoFID, 2021). A different recipe, portion of sauce or cooking method will move them, so read them as a typical estimate.

By share of the daily reference intake: vitamin B12 (0.0013 mg, 52 %), chloride (391 mg, 49 %) and phosphorus (195 mg, 28 %) per 100 g.
How these numbers were made
Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 15-796, Flan, cheese and mushroom, homemade, published by Public Health England under the Open Government Licence v3.0; this record is a calculated recipe estimate. Main data references: Updated 2014. Values are per 100 g of the edible part; a serving is 300 g, one serving, the usual UK portion for dishes. Reference intakes follow Regulation (EU) 1169/2011 Annex XIII as retained in GB law; “source of”, “high in” and “low” follow Regulation (EC) 1924/2006, assessed per 100 g. Function lines are the authorised wording from the GB register of nutrition and health claims, credited to the nutrient. Energy is rounded to the whole kcal and kJ; other amounts to one decimal, or two below 1. A trace is shown as “trace” and never gets a figure or a badge; a nutrient never analysed is left off the page. We start from the dataset’s 2,887 records and keep 2,322: records weighed with bone, shell or skin, alcoholic drinks, infant foods, brand-named products, records with fewer than eight measured vitamins and minerals and near-identical variants are left out. Group context uses the 603 dishes kept from the dataset; a rank counts only the foods with a measured figure for that nutrient. Food images are illustrations from Ingredient Atlas, released under CC0; they show the food, not the measured sample, and where no illustration of the exact food exists the nearest one is shown (here: Mushroom). Checked 5 October 2026. Contains public sector information licensed under the Open Government Licence v3.0.
