Concoct a delicious hibiscus tea, agua fresca de jamaica, sorrel or hibiscus cooler with dried hibiscus flowers. Steep or cold-brew and flavor with any number of other spices -- ginger, allspice, star anise or even pepper.
Oaktown Spice Shop has been in the Adams Point neighborhood for nine years. They focus on sourcing the absolute best-tasting version of each individual spice, then grind the spices themselves, in their shop. This means the ground spices customers find at Oaktown are bursting with flavor and are far fresher than those found elsewhere.
You can visit their own site here or find more of their spices on Keep Oakland Alive.
