Your senses are a surprisingly good first filter. Be wary of sweets that look unnaturally bright, especially in yellow and orange, because that can be a sign of synthetic colours. Smell them too, since a strange, sour or soapy smell and a bitter taste are warning signs. For mawa, try the palm test. Pure mawa feels slightly oily and grainy, while mawa that feels sticky, powdery or dry may have been mixed with other things. If something seems off, don’t eat it.
