First off today I went and cooked a load of stuff using up most of my ingredients. Then I wandered round the map for a while picking more ingredients, and collecting some Snatched Pearls and other stuff of value.
Selling these things, and more food, I scraped together enough rupees to make the tower grow another stage. This gave me access to Lon Lon Meadow, which is full of evil cows and mushroom things. Wandered round there for a bit, but became a bit low on rupees so retreated to my house.
