School chalks are semi-soft liquorice sweets in white and black, made to look convincingly like real chalk. The resemblance is the whole joke: this is confectionery you could slip into a pencil case without anyone noticing. Under that disguise sits a classic liquorice flavour with a semi-soft bite, so the taste comes through at once. School chalks belong to the sweets bought first for their looks, which makes them popular with children and with anyone after something playful for a party or a treat.
