Organic white fish is the best protein source to add to first puree.
Do not introduce the fish before the age of four months. You can make this recipe only with the vegetables.
1 small sweet potato, peeled
5 oz cod fillet, skin removed
3 oz milk or water
1 carrot, peeled
1 red pepper, cored and deseeded
Place all the vegetables in a pan with water to cover them and simmer for 25 minutes until tender, then puree coarsely.
In a separate pan place the fish with milk or water and simmer for 6 minutes until the fish is cooked and flakes easily. Check carefully for bones and remove any that are found.
Add the fish and liquid to the vegetables mixture and mash with a fork or puree to the desired consistency.
