Questions about custard tart
The questions people ask about custard tart, answered from the dataset.
How many calories are in a portion of custard tart?
A typical portion (60 g, a slice) gives 165 kcal. Per 100 g the figure is 275 kcal.
Is custard tart a source of chloride?
It is a source of chloride: 226 mg per 100 g, 28 % of the NRV, which passes the 15 % threshold for “source of” but not the 30 % needed for “high in”.
Are these figures exact for custard tart?
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.
Which vitamins and minerals does custard tart have most of?
By share of the daily reference intake: chloride (226 mg, 28 %), vitamin B12 (0.0007 mg, 28 %) and vitamin E (1.8 mg, 15 %) per 100 g.
How these numbers were made
Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 11-1058, Tart, custard, large, 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 slice is 60 g, a slice, the usual UK portion for cakes, biscuits and pastries. 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 134 cakes, biscuits and pastries 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: Cream). Checked 5 October 2026. Contains public sector information licensed under the Open Government Licence v3.0.
