Calories in Jelly, Custard, Flan and Agar Agar

By NYUS Inc. · Published 28 October 2026

A bowl of jelly, a half cup of custard or flan and a spoon of agar each have a gram weight printed on their SR Legacy record page, mostly for the dry mix and for the prepared dessert. This guide gives nineteen such records from the SR Legacy table of USDA FoodData Central: eight gelatin dessert and gelatin powder records, four egg custard records, four flan records, one chocolate mousse record and two agar records, with the weights printed on their record pages. IFCT 2017, the Indian Food Composition Tables from ICMR-NIN, has no jelly, custard, flan, mousse or agar row, so this page uses SR Legacy only. Kheer and rice pudding are in our kheer guide, ice cream in our ice cream guide and cake in our cake, muffin and doughnut guide.

The short answer

By the SR Legacy records, 0.5 cup (135 g) of gelatin dessert prepared with water is 81.0 kcal, 0.5 cup (141 g) of baked egg custard 146.6 kcal, 0.5 cup (141 g) of egg custard made from the dry mix with whole milk 172.0 kcal and 0.5 cup (153 g) of caramel flan 221.9 kcal. Our reading: milk, egg and sugar decide the cup: gelatin dessert made with water is the lightest half cup on the page (23.4 kcal for the reduced calorie record, 81.0 kcal for the regular one) and chocolate mousse (202 g for 0.5 cup) is 454.5 kcal.

SR Legacy: per 100 g

Every figure below is exactly as the record page shows it. The record names are the dataset's own.

SR Legacy: per printed portion

Each figure is our arithmetic on exact weights: kcal per 100 g times the grams, divided by 100, with the exact product in the sums line and the result shown to 0.1 with half rounding up. Every weight below is printed on the SR Legacy record page; none is ours. A dry mix portion is the weight of the dry powder, not of the dessert you eat. The records also print whole-recipe and whole-package yields, which are not shown; records 169621 and 168796 print their portion as "0 cup" and are shown per 100 g only. Seaweed, agar, dried (170090) prints no household portion.

The sums: 168775 381 × 21 / 100 = 80.01, so 80.0 kcal; 168775 381 × 85 / 100 = 323.85, so 323.9 kcal; 169596 60 × 135 / 100 = 81, so 81.0 kcal; 169596 60 × 21 / 100 = 12.6, so 12.6 kcal; 169599 335 × 28 / 100 = 93.8, so 93.8 kcal; 169599 335 × 7 / 100 = 23.45, so 23.5 kcal; 169597 198 × 6.4 / 100 = 12.672, so 12.7 kcal; 169693 345 × 2.5 / 100 = 8.625, so 8.6 kcal; 169693 345 × 9 / 100 = 31.05, so 31.1 kcal; 169693 345 × 10 / 100 = 34.5, so 34.5 kcal; 169598 20 × 117 / 100 = 23.4, so 23.4 kcal; 169691 381 × 21 / 100 = 80.01, so 80.0 kcal; 169691 381 × 85 / 100 = 323.85, so 323.9 kcal; 169692 345 × 2.5 / 100 = 8.625, so 8.6 kcal; 169692 345 × 10 / 100 = 34.5, so 34.5 kcal; 169692 345 × 9 / 100 = 31.05, so 31.1 kcal; 168772 410 × 85 / 100 = 348.5, so 348.5 kcal; 168772 410 × 21 / 100 = 86.1, so 86.1 kcal; 168787 112 × 141 / 100 = 157.92, so 157.9 kcal; 168773 122 × 141 / 100 = 172.02, so 172.0 kcal; 169595 104 × 141 / 100 = 146.64, so 146.6 kcal; 169602 348 × 21 / 100 = 73.08, so 73.1 kcal; 169602 348 × 85 / 100 = 295.8, so 295.8 kcal; 167574 145 × 153 / 100 = 221.85, so 221.9 kcal; 168777 225 × 202 / 100 = 454.5, so 454.5 kcal; 169280 26 × 10 / 100 = 2.6, so 2.6 kcal.

Why these are reference rows, not your pack

• Names are the records'. No record name or portion label shown here carries a company name. "Reduced calorie, with aspartame" and the added vitamin and mineral parts of the gelatin names are USDA's own and are shown as printed; we do not say which one a packet matches.
• The custard is an egg custard. The custard rows are dry mixes and a baked egg custard from the dataset. They are not the cornflour custard powder sold in India, and we do not say that one matches the other.
• Dry or prepared. A dry mix row and the same mix prepared with water or milk are different foods: use the prepared row for what you eat and the dry row only for the powder you measure out.
• Every portion here is printed. No cup, spoon, envelope or package weight on this page is ours: each is printed on its record page, and the only weight that is ours is the labelled 100 g example in the logging section.
• The records' own notes. The record pages mark the kcal energy of 10 of the 19 records "Calculated", mark 4 as recipe-based (168787, 169621, 168796, 168777) and print no source label for the energy of 5 (168775, 169599, 169693, 169691, 169692); they are USDA values, not our measurements.

How to log it so the numbers hold

• Weigh the bowl when you can. 100 g of gelatin dessert prepared with water (our example weight, not a dataset value) on SR Legacy 169596 is 60 × 100 / 100 = 60, so 60.0 kcal.
• Pick prepared or dry, and the milk. The egg custard rows for 2% milk and whole milk differ; log the one that matches how it was made.
• Toppings are separate. Cream, fruit and sauces added on top are not in these rows; cream is in our cream and milk powder guide.
• Do not mix datasets inside one day. If you log a dessert from SR Legacy, keep to that record for the same bowl.

Where NYUS fits (our app)

We make NYUS, so read this as ours. NYUS is an AI fitness and nutrition coach in early access on Android, with no ads and no data selling. You log foods yourself by searching 8,900+ Indian and global foods or by barcode, and a weekly check-in adjusts your calories, macros and step goal once enough is logged. Barcode coverage of Indian packaged foods is not complete, so search by name when a scan finds nothing.

What this page leaves out

• A calorie target, and any claim about what desserts do to your weight or health: we have not looked up one for any person, so we give none. If you have a medical condition, ask your doctor or dietitian.
• Custard powder, blancmange, panna cotta, halwa, kulfi mixes, cheesecake, trifle and any packet or maker's dessert: no record used here. A search of the SR Legacy table on 28 Oct 2026 for blancmange and panna cotta returned no record. We did not search for halwa, kulfi mixes, cheesecake or trifle.
• Puddings: the "pudding" search returned 64 records, which we counted and did not read or list; rice pudding (168783, 168782, 169611, 169605, 168063) and tapioca pudding (169606, 169614, 170243, 168798, 169612, 169607) were found in two narrower searches and are left out.
• The "custard" search returned 14 records: 8 are used, and these 6 are left out: custard-apple 171725 (a fruit), pies 172782 and 172783, baby food 171380 and 171379, and a cream puff 167534. The "egg custards" search returned 5 (4 used, pie 172783 left out), "flan" 4 (all used), "mousse" 2 (168777 used, pie 175015 left out), "gelatin" 8 (all used) and "agar" 2 (both used).
• The "jelly" search returned 8 records, none used: jelly preserves 169642, 168145 and 169879 (jam and preserve records), jellied meats 173860 and 170202, gumdrops 167989, a doughnut with jelly filling 172759 and a company-named cranberry sauce 167804.
• Rennin (junket) desserts, 7 records: 168794, 169616, 168792, 168789, 169617, 168790 and 168793, left out.
• The "desserts" search returned 47 records, 10 used: left out are baby food (171377, 170983, 168133, 168140, 167690, 167733, 169872, 168135, 168134, 170977, 170976, 171376, 171375, 170981, 170980, 171378, 171341, 171373, 170979, 171380, 171379, 171374, 170982), dessert toppings (170865, 170867, 170868, 170866), dessert wines (175112, 173176), company-named records (170326, 168762), rennin records already named above, and 169601 Desserts, apple crisp, prepared-from-recipe; 167686 Milk dessert, frozen, milk-fat free, chocolate; 170890 Milk dessert bar, frozen, made from lowfat milk.
