A delicate lotus-seed sweet soup, simmered until the seeds turn soft and floury in a clear, light syrup. It is one of the most refined of Hue's many che, prized for its clean sweetness and faint herbal aroma rather than richness. The lotus seeds of Tinh Tam lake in Hue are especially celebrated for the dish, and it is often paired with longan, the fruit cradling a single seed.
Che hat sen is associated with Hue and its court-influenced sweet tradition, in which lotus, a flower rich in Buddhist and royal symbolism, featured prominently. Lotus seeds from Tinh Tam lake, historically a lotus pond linked to the Nguyen court, are the most prized for the dish and lend it its reputation as a refined, almost ceremonial sweet. As a simple lotus-seed sweet soup it is also made throughout Vietnam, but Hue's version carries the strongest claim to prestige.
The lotus seeds are tender and break to a soft, floury, faintly chalky center, with a clean nutty taste and the gentle bitterness left if the green germ is kept. The syrup is thin and only lightly sweet, served warm or over ice, sometimes scented with pandan. Where many che are dense with coconut and beans, this one is quiet and clear, almost soothing, the sweetness restrained so the lotus flavor comes through.
The technique is gentle simmering and patience. Lotus seeds, fresh or dried-and-soaked, are cooked slowly until they soften without breaking apart, since boiling hard splits them and clouds the syrup; the green germ in the center is usually removed to take out the bitterness, though some keep it on purpose. The sugar is added only after the seeds are tender, because cooking them in syrup from the start toughens the skins and stops them softening. The aim is a clear syrup and whole, intact seeds with a soft floury middle.
Variations
The plainest version is lotus seeds in clear syrup; the most famous Hue pairing is che sen long nhan (or nhan long hat sen), in which each lotus seed is tucked inside a pitted longan, so the fruit's sweetness frames the seed. Other versions add lotus seeds to mixed che, combine them with white fungus or sugared kumquat, or scent the syrup with pandan. It can be served warm in cool weather or chilled over ice in the heat.
