Gachak
Warm toasted sesame and a ready rolling surface give time to spread the slab.
16 thin sesame-jaggery pieces
About 60 minutes including cooling. Sugar stages depend on temperature and moisture rather than a guaranteed number of minutes. One tablespoon = 15 ml; one teaspoon = 5 ml.
About Gachak
This gachak is a thin sesame-and-jaggery slab. It is distinct from the peanut-and-white-sugar chikki entry and the small rounded sesame rewri. Jaggery varies in moisture and impurities, so a cooled-water brittle test backs up the thermometer. The sesame is toasted first and held warm; cold seeds would make the syrup seize before the slab could be rolled. Work with a small batch and two paper sheets rather than attempting a very large hot sheet.
Kitchen testing has not been documented for this recipe. Cooking times are estimates and vary with the stove, cookware and batch size. Follow the doneness checks in the method.
Make it work for your kitchen
Original quantities serve 16. Cooking times, pan size and frying-oil depth do not scale, cook in extra batches instead.
Before you start
Set up first
Prepare paper, rolling pin and a bowl of cold water before heating sugar. The cold water is for testing tiny syrup drops and must be kept away from the hot pan.
PreparationSet up the equipment
Have the following tools ready before starting: Digital scale; Heavy saucepan; Silicone spatula; Sugar thermometer; Paper-lined tray; Rolling pin where specified.

Before cooking
Step-by-step cooking method
1 Toast sesame
Dry-toast sesame in a heavy pan for 4–6 minutes, stirring until fragrant and lightly golden. Do not brown deeply.
2 Toast sesame (continued)
Transfer to a warm bowl. Grease two sheets of baking paper with 5 g ghee.
3 Melt jaggery
Combine jaggery and water in the pan and heat gently until melted. If visible grit remains, strain while fluid into a clean pan.
4 Melt jaggery (continued)
Stir in remaining 5 g ghee and cook to roughly 145–150°C. Drop a little syrup into cold water; once cold it must snap, not bend.
5 Mix and roll
Turn off heat and stir in sesame and cardamom quickly.
6 Mix and roll (continued)
Transfer to the paper, cover with the second sheet and roll with a rolling pin to about 5 mm thick. Keep hands away from escaping hot syrup.
7 Score and cool
After about 2 minutes, peel back the top paper carefully and score 16 rectangles with an oiled knife.
8 Score and cool (continued)
Leave flat 30 minutes until fully cool, then break along the lines.
Chef’s tips
- Warm toasted sesame and a ready rolling surface give time to spread the slab.
- Use a thermometer clip so the probe does not touch the pan base.
Common mistakes & quick fixes
- Chewy slab
- Jaggery syrup was undercooked or humidity softened it. Use the fully cooled snap test; do not judge a warm drop.
- Burnt bitterness
- Jaggery darkens quickly near the endpoint. Remove from heat promptly and never try to mask burnt syrup.
Variations & serving ideas
Defined version: This is sesame-jaggery gachak; peanut and sugar versions have separate formulations.
Perfect result check
| Texture | Thin pieces snap cleanly and hold sesame throughout rather than shedding loose seeds. |
|---|---|
| Portioning | Sixteen rectangles are a guide; keep the sheet uniformly thin. |
Storage & reheating
| Airtight in a cool dry place | Best within 5 days | Cool completely before sealing. Keep away from humidity; this is a quality window, not a validated commercial shelf life. Refrigerate milk-containing patisa if keeping longer than the day of preparation. |

Know when to change the heat
| Stage | Heat | What to look for |
|---|---|---|
| Toast sesame | Low heat | 4–6 minutes |
| Melt jaggery | Medium-low heat | 8–12 minutes |
Helpful answers before you cook
Can I use soft jaggery?
Yes, but it may take longer to reach the snap stage because more water must evaporate.
Why is my slab sticky the next day?
Humidity draws water into sugar. Store fully cool pieces airtight and avoid a damp kitchen.
Can children help roll it?
Keep children away from hot syrup; portioning can wait until it is fully cool.
