Almost every traditional Bihari sweet uses gur — jaggery — rather than refined sugar. Thekua, kasar laddoo, tilkut, the rasiao-kheer eaten on Kharna: all of them are jaggery-based.
This was not a health decision. It was simply what was available. But it turns out the older choice holds up rather well.
What jaggery actually is
Jaggery is sugarcane juice that has been boiled down and allowed to set, and that is the whole process. Nothing is removed.
Refined sugar starts from the same juice but goes considerably further — it is clarified, filtered, crystallised and bleached until only sucrose remains. Everything else present in the cane is stripped out along the way.
That difference in processing is the entire story. Jaggery retains the molasses; sugar does not.
What survives in jaggery that sugar loses
Because it is unrefined, jaggery keeps small quantities of what was in the cane:
- Iron — the most notable. This is why jaggery is traditionally given to women after childbirth and to anyone recovering from illness.
- Potassium and magnesium — present in modest amounts.
- Plant antioxidants — polyphenols from the cane, entirely absent in white sugar.
- Trace calcium and phosphorus.
An honest caveat: these amounts are small. Jaggery is not a supplement, and you would need to eat a great deal of it to meet any daily requirement. The realistic claim is that jaggery is less empty than refined sugar — not that it is nutritious.
The digestion difference
Refined sugar is close to pure sucrose and is absorbed very quickly, producing the sharp rise and subsequent crash most people recognise.
Jaggery contains sucrose too, but alongside fibre traces and minerals that slow absorption somewhat. The rise is gentler. This is why a jaggery-based sweet tends to feel more settling and less likely to leave you hungry an hour later.
This should not be over-claimed. Jaggery still raises blood sugar meaningfully and is not a free pass for anyone managing diabetes. Anyone with blood sugar concerns should treat jaggery as sugar and speak to their doctor. The difference is one of degree, not kind.
Why it tastes better in traditional snacks
Set nutrition aside for a moment — jaggery simply makes better thekua.
Refined sugar delivers one note: sweet. Jaggery brings caramel, a faint smokiness, a mineral edge, and a mild bitterness at the finish from the retained molasses. That complexity is why jaggery sweets do not feel cloying even when they are quite sweet.
It also behaves differently in cooking. Jaggery syrup is more viscous than sugar syrup, giving thekua dough its characteristic density and helping the finished piece hold its shape and stay crisp. Substitute sugar into a thekua recipe and it comes out paler, lighter and noticeably less interesting.
You can read about how the syrup is prepared in our step-by-step thekua method.
Choosing good jaggery
Not all jaggery is equal, and adulteration is common.
- Colour: genuine jaggery is dark brown to deep amber. Bright yellow or pale blocks usually indicate chemical bleaching.
- Texture: should be firm but yield to pressure. Rock-hard or unnaturally glossy suggests additives.
- Taste: a clean caramel sweetness with a slight mineral finish. A chalky or metallic aftertaste is a bad sign.
- Source: jaggery from smaller local units is generally less processed than large commercial output.
What this means for what you buy
Many commercially sold thekua and Bihari sweets have quietly switched to refined sugar. It is cheaper, more consistent, and produces a lighter colour that some buyers mistake for freshness.
The result looks similar and tastes noticeably flatter. If a thekua is uniformly pale gold and tastes purely sweet with no depth, sugar is the likely reason.
Our thekua is made with pure jaggery, as it always has been in Bihar — no refined sugar, no artificial flavours, no preservatives. It is why the colour is deeper and the sweetness rounder than the packaged alternatives.
