Norwich City co-owner Delia Smith said she was "saddened" Ipswich Town had not apologised after her car was hit by a can of lager outside their ground.
People chanted "scum" and a can struck the bonnet as the celebrity cook arrived for a derby match at Portman Road on 16 December.
In a statement, the 82-year-old thanked opposition fans for their messages of support but appeared to criticise the club for not speaking out.
Ipswich Town said it would not comment.
Other missiles appeared to be flung towards the BMW as it made its slow approach to the ground, while flanked by police and security.
