A 2-year-old boy from an urban slum in Delhi is enrolled in the ICDS scheme. His mother brings him to the Anganwadi centre for supplementary nutrition. On assessment, he weighs 9 kg (between 50th–75th percentile for age) but has a mid-upper arm circumference (MUAC) of 11.5 cm. His haemoglobin is 8.5 g/dL, and he has angular stomatitis and follicular hyperkeratosis. The Anganwadi worker notes that the child is being fed on Take-Home Ration consisting of fortified wheat flour and fortified rice. What is the MOST appropriate micronutrient fortification strategy for this child's THR?
