Is there a specific food item associated with Saptami Shradh?

The Garuda Purana mentions that food preparations made with sesame seeds (til), rice, and ghee are universally appropriate for all Shradh tithis. For Saptami specifically, some regional traditions include offerings of khichdi (rice and lentil porridge), which is considered easy to digest and associated with simple, sattvik nourishment appropriate for ancestral offerings.
